Well, there were certainly some twists that I did not see coming in this story. It seemed like it would be a simple murder investigation - if there is such a thing. But as the Casey and Tracy did their due diligence and followed the clues as they were presented, the danger also increases. This is one of those thrillers that you won't be able to put down.

Time is passing in the Outer Banks. Casey and Jericho are now foster parents to Tommy and Tabitha, having discovered that they have no family after the events of Two Little Souls. But crime, and their jobs, still does not stop for anyone.

A mysterious death of a scuba diver near a shipwreck raises red flags, leaving Casey and Jericho to to try and discover what happened. While a scuba death doesn't necessarily seem like foul play, markers on the victim lead to more questions, coupled with an odd find on the ocean floor. As the team investigates, another body is found and Jericho is attacked, leaving Casey down her most important partner and depending on others to help her solve the case.

B.R. Spangler has done it again. I absolutely love this series, both the mysteries and the relationships between Casey, Jericho, Tracy, and the rest of the characters. This one is definitely a page turner, with twists and turns. Every time you think you know who the killer might be, another clue drops and the reader is right back to the drawing board. I'm also loving the addition of Tommy and Tabitha to Casey and Jericho's family, seeing their circle expand and wondering how the kids will fit in in future novels.

Casey solves mystery crimes in the Outer Banks, but this latest book has her underwater.
The action is non stop from murder under water, the sea coughing up another body, and buried treasure!
I loved all the allusions to history and the sunken treasure.
I also liked the new venue of off the land because it added new elements of excitement.
I was completely stumped about the villain (s) until Spangler revealed it.
I love this series and trying to put together the clues alongside Casey and Jericho.

4.5⭐

Detective Casey White returns in a story. That's gripping and intriguing. 

As Casey and her investigator Tracy are going to put not only their own lives in danger. But the lives closest to them.

When a reunion of sorority sisters ends in tragedy and what seems a simple drowning is anything but.

And when the victims husband arrives in the Outer Banks, he soon becomes a suspect.

But then someone tries to run Tracy and Casey of the road and that's only the start.

As the team learn of a treasure hidden at the bottom of the ocean. A treasure someone is willing to kill for.

But who?

And can Casey and co find out before one of her team or someone she loves end up dead?

And with twists and turns. Not to mention danger. This was a cracking addition to the series, and I really enjoyed the whole treasure aspect of it. Which I found really fascinating and I would happily recommend it to others.

Our Sister's Grave is book 10 in the Detective Casey White series by B.R. Spangler.
I will anything written by Spangler! His crime thrillers always make me lose all track of time.
The book is nerve wracking, heart pounding and I read it in one sitting.
And mystery itself is very gripping, and the writing solid. This is a compulsive, addictive and fast-paced police procedural with a well-crafted plot with interesting and engaging cast of characters.
A highly entertaining and absorbing police procedural which I recommend without any hesitation.

Thank You NetGalley and Bookouture for your generosity and gifting me a copy of this amazing eARC!

it’s always a pleasure to travel to Outer Bank because you know you will read a good story and a solid mystery.
Casey, Jericho, and their adopted children are sort of book friends you are happy to meet and you always root for them hoping nothing too serious will damage them.
This is a twisty and complex story, there’s some sad moments, I felt for the characters and was surprised by the twists.
There’s hope and there’s darkness all in a gripping and well plotted story I read in one sitting.
Highly recommended.
Many thanks to the publisher for this ARC, all opinions are mine

A reunion of sorority sisters ends tragically when Karol Witney drowns during a planned diving and scuba expedition. However, the medical examiner doesn’t think this was a simple drowning. Karol’s face mask was forcibly removed and there is a fresh handprint on her wrist. X-rays show that she has been the victim of domestic violence so when her husband quickly shows up at the police station, Detective Casey White and her team consider him to be a strong suspect. Things are not that easy and soon Casey, her fiancé Jericho and daughter Tracy are enmeshed in a deadly mystery above and below the water.

Our Sister’s Grave is the tenth in this excellent series. The plots keep growing stronger, the characters have become so familiar we feel we’d know them if we saw them on the street and the Outer Banks always provides an atmospheric location. I’m looking forward to the Next Casey White thriller. 5 stars.

Thank you to NetGalley, Bookouture and B.R. Spangler for this ARC.

Sorority sisters go for a diving excursion. One ends up dead and it appears it was no accident. The victim has signs of past abuse. Could there be a connection? The victims husband is found to have been in the area before his wife was found dead. Then his body is found dead. Can Casey find the answers before there are more dead bodies...

The chilling prologue sets the mood for the remainder of this book as the victim drowns. This eerie scene gives me goosebumps just writing about it.

When Detective Casey White is called to the scene of the drowning, she is a little confused as to why she has been called to the scene until she sees a handprint on the ankle of victim. Karol did drown, but it was not an accident. Eight sorority sisters have met for the weekend for a diving excursion, but one will not return. I soon learned that everything was not as it first appeared with this group of ladies. As Casey and company start their investigation, they realize that their lives are in grave danger.

The crime scene is at the bottom of the ocean which means they will have to literally dive into the scene of the crime. When Casey's future husband, Jericho, is attacked underwater and is fighting for his life, we know this is getting serious. Someone is hiding something, and they will kill anyone who gets in their way.

Once again Casey White shines as her character is growing in her personal life. We already know she is a crackerjack investigator. The tension was palpable as the desperate need for justice was evident at all costs. I enjoy all of the characters in this series. The characters mesh well together as a crime fighting team. As always this is a well written police procedural with an interesting plot line that will keep you wanting more.

Thank you to Bookouture and NetGalley for this ARC. I am leaving this review voluntarily.

Omg. This book was so good I couldn’t stop reading it! Before I requested it I wasn’t aware that it was apart of a series but I was still able to read along and understand. I’ve found myself to be a new fan of BR SPANGLER. The book kept me hooked from beginning to end! I absolutely love Casey & Jericho, what a duo! This book has all the things I look for in a mystery/thriller! Suspense, plot twists, secrets, etc. I can’t believe this is the first time I’ve read a BR Spangler book. So grateful for the opportunity to review this ARC.

Brief summary: when a woman turns up dead after scuba diving Casey & her team are now investigating. Just when they think they have it figured out, a monkey wrench ruins everything & they have to restart! Kept me guessing!

I’ve done every book in this series and was so excited to be chosen to do this ARC. This book didn’t disappoint! I wasn’t much of a fan of Casey in the beginning of the series but I have grown to like her. I feel she gets better each book. I love that you find out they want more with Thomas and Tabitha. The lost treasure story line was cool! It’s not like any of the other books which was nice. I felt everyone grew a little closer in this book. I do wish something would happen for Tracey and Casey. That slow “relationship” I feel has been dragged along. Something needs to progress there. This was a really good book and I look forward to book 11!

Pulse Pounding Thriller In And Out Of The Water. This is one of those coastal murder tales where there is actually quite a bit happening both in and out of the water - and our team is right in the thick of all of it, after a diver dies underwater. With this tenth entry into the series - written loosely enough that if one doesn't mind spoilers about the team's relationships, nothing about (most) of the prior mysteries is spoiled here, meaning it is mostly ok for new fans to start here and work their way back, should they so choose - Spangler actually manages to incorporate a few things not seen in prior books in this series, including a few particular cultural touchstones that it is genuinely surprising that it took him this long to use, given the region he has chosen to set this particular series. And man, when he *does* incorporate them... he almost makes me want to drive up I-95 a few hrs and get to the Outer Banks this weekend myself. Even though I am in no way, shape, or form a diver of any sense involving diving underwater. :D

Overall another solid entry in this series, one where yet again the stakes are raised in so very many ways. Very much recommended.

I really enjoy the Casey White series and this novel does not disappoint. Set around the World of diving, it is unusual for that and is well plotted throughout. Buoys To Seamen as a boat name was pure genius. Very enjoyable read.


Thanks to NetGalley and Bookoutre for providing me with an Advance Reader's Copy in exchange for an honest, unbiased review.

Sibling rivalry can be murder, but when a group of a group of 8 sorority sisters meets up for a reunion, the last thing they expect is for that diving excursion to end in the death of one of their number. And the fingerprints on Karol Witney's ankles clearly indicate that this was no accident.

While I have not read other books in the Casey White series before, this latest instalment works quite well as a stand alone novel. The book is entertaining and the plot has some unusual twists.

For a start, how do you solve a killing that is committed underwater? That is the situation that Casey and her boyfriend Jericho find themselves in. And when they go diving for any remnant of evidence, the attack on Jericho makes it clear that the killer is far from done...

This is a well-paced and satisfying murder mystery, with some nice extra touches. It gets 3.5 stars.

A underwater murder and attempted murders has Detective Casey White trying to figure out how to work a crime when all the evidence is under water and most probably, washed away.
There is a lot going on within the story. Many suspenseful moments!
Another great installment in the Detective Casey White series.
Thank you to NetGalley, Bookouture and the author for the opportunity to read this book for my honest review. All opinions expressed are my own.

A good read. The plot was a good one and well written.
A woman dies while scuba diving. Now Casey must figure out to work a crime when it’s committed under water.
Add in abuse, gold and people hiding the truth, you have a very interesting read.
I love seeing Casey and Jericho work together.
Many thanks to Netgalley and Bookouture for the chance to read and review this one.

This is book 10 in the ever improving Casey White series but it can be read as a stand alone. The characters are well developed and the plot is well researched. When a woman is killed whilst in a deep sea dive, Casey and her partner Jericho are investigating. I like the dynamics between them, Casey is more settled in this episode and hoping to adopt two children. The plotting was good, centred around greed and jealousy, with a bit of history thrown in, and the pace was fast with some unexpected twists. Overall, it is a good mystery which I would recommend. Thanks to Net Galley for my ARC.

I would like to thank Netgalley and Bookouture for an advance copy of Our Sister’s Grave, the tenth novel to feature Detective Casey White, set on the Outer Banks, North Carolina.

Karol Witney is holidaying with seven of her sorority sisters when she drowns on a dive. The medical examiner gives Casey evidence that Karol was murdered and her death is not the accident it first appeared. When Casey goes diving to investigate the crime scene her fiancé, Jericho, is attacked. Then another body is found.

I thoroughly enjoyed Our Sister’s Grave, which has an eventful plot with plenty of twists and turns. It is told from Casey’s first person perspective so the reader gets a close look at her reactions to the many events and danger she faces. It also means that the reader knows what she knows, allowing scope for guesswork and interpretation of the known facts. It makes for an immersive read.

This is an interesting read. There isn’t one through line in the novel with several people committing crimes as part of the bigger picture. I was astonished at the number of arrests and how it all comes together. Hats off to the author for such an unusual take on a murder. The links between the characters take some swallowing, but who needs reality when the entertainment is so good?

The novel is fast paced with a series of life threatening events and some unexpected twists that give Casey pause for thought and some new permutations to consider, even if the motive turns out to be an old standby that has existed since time immemorial.

I like Casey White. Now that she has found her daughter, a thread which ran through the early novels, and has found happiness with Jericho she seems calmer and more clear sighted. Even fostering two children can’t upset her equilibrium (not sure that’s possible).

Our Sister’s Grave is a good read that I have no hesitation in recommending.

Our Sister’s Grave, the latest in the Casey White detective series, starts with a tension-filled prologue, setting the scene that leads to Casey’s next case. The action continues throughout the book but is also well-balanced with descriptions of Casey’s home life with Jericho and their two foster children.

Spangler does an excellent job immersing the reader with vivid descriptions of the Outer Banks and explaining the workings of scuba diving and even some shipwreck history. And as always, the character development of Casey and Jericho is first rate. This is all done while creating a fast-moving story that will have you reading just one more chapter… For those new to the series, Our Sister’s Grave can easily be read as a standalone novel. But I know I’m looking forward to Casey’s next adventure!

Thanks to NetGalley, the author and Bookouture for the opportunity to read this digital ARC.
