What a fun book to read! Lost in Time is the first book I’ve read by the author, and I thoroughly enjoyed it.

Sam Anderson,one of the creators of the Absolom machine used to transport convicted killers into,the past of an alternate universe, self confesses to the murder of one of his colleagues in order to protect his daughter from being convicted. The story then takes parallel tracks, following Sam as he tries to survive in the late Triassic era, and that of Adeline, his nineteen year old daughter, who seeks the identity of the killer. It’s then that first of the many twists occurs, many of which I never saw coming. Lost in Time then takes many of the conventions we are used to in time travel stories, and flips them on their heads.

A minor annoyance was that each short chapter in the first half of the book ended in cliffhanger style. Otherwise, a fast and very entertaining read.

My thanks is to Head of Zeus and to Netgalley for providing an ARC of the book.

4.5*

This was such an enjoyable and fast-paced book!!

We follow a scientist named Sam and his daughter Adeline, who are arrested for the crime of Sam’s colleague. But the worst part is, criminals are sent back in time to the jurassic period, never to return. When Sam takes the blame and ends up 200 years into the past, Adeline will do whatever it takes to save her father.

Starting off, I thought the writing was very simple and easy to read. The pacing was fast- like really fast- so I was shook when we already got to the jurassic period. We jump from Sam and Adeline’s POVs, and I think the author did well to cut off Sam’s POV quite early, because the story got WILD.

I did not expect to love this book. Adeline begins to search for the real killer, doubting all her father’s friends. She becomes determined to save him, while living with Danielle, one of the other scientists involved in the invention of this strange time machine. I did NOT see those plot twists coming. This book definitely messes with your brain, but it’s super easy to follow.

Adeline was definitely my favourite. I’d say go into this book without any information, and you’ll really enjoy it. it’s got an almost scary dystopian vibe to it, that makes you fearful of the future. The technology is explained well, and I liked the time travel aspect. There isn’t a lot of character development, but I liked the relationships and how they were portrayed. This is a plot-driven book through and through, and definitely one of the best time travel novels out there! I can’t wait to see what this author does next!

Going into this novel I expected some curve balls. What it threw at you I would have never seen coming though. While within the book each chapter ending tries to give you little cliffhangers too.
Lost in Time is told from two perspectives. That of physicist Sam Anderson and his daughter Adeline. Overall this separation of view points helps fill in missing pieces and emotional coverage of what is happening very well.
Overall I think this was a well done book. It is said to be a one shot but I feel the way he ended the book while a good closing left room for more story to be told.

A solid 3.45 here from AG.

What we have here is a supposed murder mystery under the guise of creating a better humanity by giving people a second chance - on an idyllic island (no less)

Throw in some time travel, dinosaurs and some crazy quantum entanglement theories, and you have a tale that was often fast paced and thrilling - especially with all the technology.

It's good.

Best read in front of a time machine on an island in the Pacific.

Thanks to NetGalley and Head Of Zeus for this ARC.

_Lost in Time_ starts with a mystery (who killed Nora?), involving likeable characters who can’t be as good as they seem, and others with secrets they try to hide. But as the narrative continues, there are enough twists and turns to keep you guessing. I appreciate a time travel story that has suspense without a lot of gratuitous violence. There was an interesting focus on causality and the relationship between past and future. Once I started the book, I finished it the next day because I just wanted to find out what happened next (or before?!).

Thanks to the publisher and NetGalley for letting me read an advanced copy of the book.

I loved the premise of this book, but I have to be honest. It had serious obstacles that I struggled to overcome. The most frustrating was the characters constantly talking around information to keep it away from the reader. They knew what they were talking about, but the reader was intentionally being kept in the dark. It would be like talking about Dave's restaurant, the burger place and the restaurant named after his daughter to reference Wendy's, instead of just saying Wendy's.

I understand the value of a big reveal and keeping twists secret, but there are better ways to do it that telegraphing the importance by bringing attention to it then ignoring it.

Thank you #NetGalley and #HeadofZeus for sending me an ARC of #LostInTime by #AGRiddle.

There is so much to digest with this book it is hard to know where to begin this review. This is an excellent story but it is long and arduous at times. To have the level of imagination that A. G. Riddle is quite impressive. I have read a few other of his stories and they are all like this. Captivating, thrilling, immersive and detailed.

Lost in Time is a time traveling, murder mystery and drama filled story. I have never read anything like this before. This is a four part story.

So much happened in Part One. Scientist Sam Anderson, widower, and his daughter, Adeline, are accused of murdering Sam’s co-worker, Nora. Who also happens to be in a relationship with Sam. Nora’s murder is the first murder in Absolom since the punishment of major crimes were introduced. The punishment…you are sent back in time to an unknown location and time.

Part Two is a split between the lives of Sam and Adeline living with the aftermath of their choices made in part one.

Part Three is an action packed and insightful section. I was on the edge of my seat the entire time. I thought I had it all figured out, but I so way off to the conclusion of this mystery!

Part Four is the wrap of everything that happened to a wonderful and perfect conclusion. There is no other ending that could satisfy this story.

A.G. Riddle has once again written a story that is original and mesmerizing. I will always be on the lookout for his books.

A. G. Riddle writes an intriguing time travel novel using an imaginative twist. In the future, individuals convicted of murder are sent back 200 million years with no resources. This story follows what occurs when an innocent man is sent back and how his family and friends attempt to correct the injustice.

Mr. Riddle concocts an impressive plot that keeps readers turning pages as each unexpected twist grabs their attention. A remarkable adventure that whets the appetite for more.

Lost in Time has a great cover and a great premise. Unfortunately, it doesn't quite live up to them, but it's solid popcorn fun.

The Absolom, a time travel device, allows governments to imprison criminals in the prehistoric past. One of its inventors, Sam Anderson, is arrested and accused of killing Nora Thomas, his lover, and co-inventor of Absolom. He didn't commit the crime but must take responsibility for it - or his daughter Adeline will be framed for it.


The government uses Absolomn to send Sam to the Triassic period, where he has to deal with dinosaurs, lack of food, and earthquakes. His arc resembles a blend of Lost and Jurassic Park but is much more bland and streamlined.

In the present (sort of) timeline, Adeline is trying to find the real killer of Nora and find a way to rescue her father. There's a massive twist at brewing, so I'll stop with the synopsis. Suffice to say, all of Absolom's creators and investors hide secrets and painful pasts.

A.G. Riddle understands the market and knows the tastes of fans of techno-thrillers. He knows how to mix simplistic science with family drama and create uncomplicated but relatable characters. I mentioned that the creators of Absolom have secrets, and they do. Only none of them are truly nefarious, and their actions are driven by grief, compassion, and the need to atone for their sins.

The author excels at delivering short chapters with mini-hooks that force readers to read "just one more chapter." Good twists and personal stakes add to the excitement.

Still, I have a few criticisms of the book. First, Riddle's writing style is bland and clinical, and his dialog often seems unconvincing ( subjective ). The story and characters lack nuance, but that's not necessarily a bad thing because it makes the book easy to read for a wide audience. It just wasn't enough to excite me. I have a problem with the logic of sending depraved criminals to prehistoric times and with the logistics of time travel. It's not a deal breaker, though. But the biggest problem I have concerns the ending, and it's the kind of a problem I can't discuss in a review. Suffice to say, I'm not a fan of micro-utopias.

In all, Lost in Time is a fun popcorn read with both emotional and scientific thrills and well-placed twists. Fans of fast-paced techno-thrillers should give it a go.

"Lost in Time" was a frustrating read for me. It had the feel of being written by an over-enthusiastic teenager, with too much repetition (small annoyances) and questions that rose that could have been answered much sooner. Still, it was fun to read... until it kind of collapsed into a brain-mushing spoof. There wasn't anywhere near enough of some characters, and the "feel good" ending felt really out of place. I'm sure heaps of people will enjoy this book much more than I did.

My thanks to the author, publisher, and NetGalley. This review was written voluntarily and is entirely my own, unbiased, opinion.

In the near future, Dr. Sam Anderson and five other scientists invent a time travel machine. It is used to send convicted prisoners back to the time of dinosaurs, I guess a more hands-off kind of death sentence. Sam and his daughter Adeline are accused of murdering Sam’s colleague and girlfriend, Nora. Sam confesses to the crime to spare his daughter and off he goes. In short, terrifying chapters we alternate between Sam’s attempt to survive amongst the dinosaurs and then Adeline’s investigation of the murder of prove her father’s innocence and bring him back. It would seem that the murderer must be one of the other scientist inventors of the time machine, and they all have secrets to hide and perhaps a motive for murder. An enjoyable but strange mash-up of mystery, sci-fi time travel, and a survival story.

Another wild ride from author A.G. Riddle. I read the description for the book and thought sci-fi? Mystery? Thriller? Yep, yep, and yep. If you are looking for great ‘literary fiction’ get out now, but if I are looking for a crazy rollercoaster ride then hop on board. This is the literary equivalent of a summer blockbuster ‘popcorn’ flick…and given the depressing news that seems to be all you see on TV 24/7 lately, it was exactly what I needed: a nice diversion, a short break from reality. Lost in Time features a cool cast of characters with a wild and relentless storyline that is hard to put down. Definitely wouldn’t mind seeing Amazon or Netflix adapt this into a limited series. 4.5 stars. I’d like to thank Head of Zeus and NetGalley for allowing me the opportunity to read and review an eARC of Lost in Time.

A twisting turning thriller that will keep you guessing throughout, this book is a great read! A group of scientist come together to try to create a machine (Absolom) to improve shipping goods faster. They hope to be able to send goods through time (like a transporter), but it failed. They could send things back in time but the things went to a parallel universe. A program was developed to send criminals back a billion years for capital offenses. One of the scientist is murdered and her colleague is convicted and sentenced to Absolom. The remaining scientists scramble to solve the murder and try to get their colleague back. There are all kinds of twists in this plot and you never quite figure out what or where it is going but the read is fantastic!

The best book by this author so far! And the best book of the many I have read so far this year.
I have been reading this author's books for quite a few years, and they have just got better and better!
This was a book of many parts, as I love action I did enjoy the earlier parts a lot, and at first was a little surprised when there was such a change of pace. But I suddenly found I was just as engrossed in the story then as the earlier, more action-filled part.
I did love how twisty this novel became, and how most of the issues that I could find with the story got dealt with at some point. I found it nicely clever, plenty of twists and turns in the story, and with an outcome that I think very few will guess. And it is So Nice to not be able to predict the outcome!
Gerry Riddle is now firmly back in my select group of favourite authors, and I can't wait to see what he comes up with next!

Lost in Time by A.G.Riddle is a timey-wimey, twisty adventure/mystery story. I enjoyed it a lot.
There isn't really much to compare it to to let you know what to expect. The synopsis gives you a little bit but the actual story is a lot more. Sam and his daughter Adeline (Anagram for another character-or vice versa?) are our time lost characters and to say to much more would spoil things.
I think that the ending could be used as a spring board for a follow up book and I hope it is. There are some scenes at the end that seem to repeat but they logically need to due to the nature of the story. It is a fun story that will have you guessing up to the end.
Thank you to #NetGalley, #HeadofZues, and A.G. Riddle for the ARC of #LostinTime.

So, this was from a standing debate with a friend over the quality of self-published works. My friend (a self-published author himself) posited that the quality is just as good as traditionally published work, citing a list of authors who started off self-publishing and they got famous. Literary giants like E.L. James, that is.
Riddle was on that list so when his latest showed up on Netgalley, I figured I’d check him out. Sure enough, I stand strong on my position. Riddle, like James, like other similar authors, may have a very good understanding of the current market, but he’s probably never going to be accused of being a great writer.
Because he isn’t, not really, more like an author. Someone who can come up with the sort of ideas that get the general audience all steamed up and then cobble it together into a book, one flat serviceable sentence at a time. As this techno-thriller proves so perfectly.
The idea behind it is huge and bombastic, straight out of Michael Bay’s catalog and movie adaptation-ready. A man accused of a crime he didn’t commit is sent back in time because apparently that’s what they do to criminals in that reality.
Yeah, it’s one of those things that totally doesn’t hold up to overthinking. So there he is, with the dinos (and there’s sadly not enough of it), while back in his timeline his young daughter is fighting to solve the murder and prove her father’s innocence.
The twist is that her father is actually behind the technology that enables time-traveling and it was meant to be something different originally, but there it is.
Enter some pseudo-scientific babble, lots of business jargon, some dubious time-traveling logistics and paradoxes and a bunch of suspense, et voila, you got yourself a book. A much too long of a book for the quality of writing, but at least it reads quickly, due to its whambam thriller-pace.
Cardboard characters all around, the set is practically flammable with them. Nothing special, but lots of things in it that sell. An imminently marketable feature. Not something to love. Probably just waiting to be adapted into something starring Chris Pratt. Read at your own discretion. Thanks Netgalley.

A G Riddle has done it again. This time in a stand alone book that is interesting and thought provoking. A very enjoyable read and I would highly recommend this book.

A.G. Riddle is a great science fiction writer. I have read most of his books and have appreciated all. I enjoy time travel books and this is a thriller! Riddle keeps you guessing with twists and turns until literally the last page. It's a excellent book and well worth the read.

I hate to do this...but I DNF-ed at 20%.
The writing style was not doing it for me. I found the dialogue static and unnatural. The worldbuilding was weak. Almost read like a Sarah J Maas book. I'm still giving it three stars because I think this book has great potential. The idea is wonderful, but the setup is absent.

When his daughter Adeline is accused of murder, Sam confesses to protect her. But in the near future, murderers are not sent to jail, they are sent to the past. Sam's punishment finds him stranded in the Triassic period, while his daughter desperately tries to clear his name.

This was a really interesting book, which turned out very differently to how I'd expected. The mystery was engaging and the twists kept coming until the very end. I personally found the very end of the book to be a little bit of a letdown, but everything leading up to it was a masterpiece! I will definitely be looking up more of the author's work!

I received a copy from the publisher in exchange for an honest review.
