Thank you to #NetGalley for the DRC of #TheMedusaProtocol. The opinions expressed here are entirely my own.
A found family story about world-class assassins in recovery (assassins anonymous)? Yes, Please! This is a really fun read even when it deals with some triggering topics (sex trafficking).
When Astrid stops showing up at meetings, her sponsor Mark suspects something is wrong. A cryptic message followed by a swarm of mercenaries sends them on a rescue mission. But when you're committed to not kill anymore, rescuing your friend from a black site prison compound is a lot more challenging.
Looking forward to checking out the first book in the series and hoping for more to come. Highly recommend.

The Medusa Protocol is the second book in the An Assassins Anonymous series. This series follows retired assassins who have formed an AA support group. I really love this series. The books are fast paced and very entertaining to read. I highly recommend starting with the first book to understand the characters better, and I hope Rob Hart continues to write more in the series. Thanks to NetGalley and PENGUIN GROUP Putnam for the ARC in exchange for my honest review.

The second in a series about former assassins in a 12-step program, this one distinguishes itself by weaving the past, via ever-enlightening backstory sequences, with the present’s current emergency. While the uniqueness of the premise of this group of ex-assassins is certainly a hook, it is the evolving nature of their interactions and relationships that is the unexpected yet satisfying draw here. This group, made of former colleagues, profession rivals, and unfortunately sworn enemies, is at times combustible as they navigate acting as a team to try and save one of their own while strengthening the bonds of their shaky yet developing “family.” Full of interesting and quirky characters and fast pacing, this is perfect for fans of the books by Duane Swierczynski, Tom Straw, Lou Berney, or Steve Hamilton.

Thank you to the author, publisher and NetGalley for the ARC to this book.
This is Book #2 in this series about a group of reformed assassins who have created a rehab group inspired by AA for killers who no longer want to kill. This is a short book but a very fun read as we delve deeper into the histories and the evolution of the mindset of these assassins looking to regain their humanity. I thoroughly enjoyed the book and highly recommend it. 4 stars!

A superb series starter like ASSASSINS ANONYMOUS can be a hard act to follow, but Hart delivers another awesome installment.
In THE MEDUSA PROTOCOL, Hart uses two perspectives, following Mark aka the Pale Horse, the protagonist from the first book, and Astrid aka Azrael, the Angel of Death. When Astrid is kidnapped and taken to a remote black site prison, Mark feels compelled to rescue her. Not only does he consider her family, he’s her Assassins Anonymous sponsor. The story delves into Astrid’s past using flashbacks.
The novel is action-packed and infused with the signature dark humor displayed in the first book. For example, Astrid has a pizza with olives delivered to one of their AA meetings. Mark, who believes that only monsters order olives on their pizza, immediately understands Astrid is alive and needs help from her AA group.
The plot brings plenty of obstacles such as various people Mark and Astrid have wronged and dangers related to the island where Astrid is imprisoned. The title plays into the story in a cool way.
In my review of ASSASSINS ANONYMOUS, I called the world “John Wick lite,” and those elements are displayed in this book as well. Beloved characters such as Mark’s cat P. Kitty and former neighbor Mrs. Nguyen are included.
While the characters are well-developed and the plot well-designed and well-executed, my favorite thing about the book is how it handles addiction, the interactions between the characters, and the cool character arcs. I look forward to seeing what Hart has in store for future installments.
I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own.

A fun and charming follow up / sequel to Assassins Anonymous. Fans of Stephen Rowley will enjoy this series. You will want to begin with the first book.

The Medusa Protocol is the follow up to Assassin's Anonymous and the gang must rescue Astrid from a black site. Following the AA 12 step program, they have chosen not to kill anymore(all former assassins). The book focuses on Astrid this time and we learn more about her background and history. Mark and company must try to figure out where she is, rescue her, while not killing anyone or getting killed in the process.
My thanks to NetGalley and the Penguin Group for the ARC. I suggest reading the 1st book before you read this one.

Astrid has been kidnapped and is in some type of prison - somewhere. She has no idea who has kidnapped her or why - just that she is being tortured in some rather unorthodox ways. Obviously Mark and the rest of the group are worried. Eventually she manages to contact them and a rescue mission is launched.
I really enjoyed Assassins Anonymous so I was thrilled to hear that there was a second book. The story flips back and forth between Mark and Astrid. And we learn a lot about Astrid's history as she digs into her memories.
Just like the first story, there are overtones of John Wick, James Bond, and even a bit of Indiana Jones! (Snakes...) And some truly awful people are removed from the planet. Hart certainly left the door open for a third book so I'm hoping we will read more about this motley crew.
Thank you to the publisher and NetGalley for a digital ARC!

The Medusa Protocol has an interesting premise with a group of assassins trying to stop killing. The description of the book pretty much tells you everything you need to know until you get into the book. It is an entertaining and quick read. I finished it in two days. I would recommend picking up this book if you are in the mood for a light mystery/thriller. This is the second book in this series. I would suggest reading Assassins Anonymous first because that introduces you to the main characters.
Thank you to Net Galley for an advanced copy of The Medusa Protocol. #TheMedusaProtocal # NetGalley #RobHart

Thank you to NetGalley for an ARC of The Medusa Protocol.
The Medusa Protocol is the sequel to Assassins Anonymous, which I enjoyed.
But I have to say I liked the sequel more, which is rare.
It might be because the main character is Azrael this time, who has been kidnapped and 'relocated' to a black site prison.
As Azrael figures out an escape plan without killing anyone in the process (not easy t0 do) Mark and his friends make their own plan to rescue their friend.
I love the concept of the AA group but with former assassins trying to reform their bad ass killing ways.
How do you live a reformed life without killing when so many other people want to kill you?
The concept of remaining true to your non-killing ways even as mercs and other assassins try to kill you is a great concept.
I enjoyed the flashbacks into Azrael's past and Mark's determination to find out where she was and attempt a rescue no matter how bleak their prospects might be.
Is this hard to suspend disbelief for?
Sure, but so is James Bond and those are exciting to watch, which is one reason they're so popular.
This series is wild with assassins and bullets and fighting with a dose of painful reality offered by the AA tenets; how to do better is a day to day process and we get through it by helping and supporting others.

The first book in this series, Assassin’s Anonymous, was one of my favorite reads last year. I just loved the concept of a group of former assassins following a 12 step program. This second book was also a lot of fun and I really enjoyed learning more about one of the characters from the first book, Astrid, while still hearing about Mark’s journey to recovery as well. This one was perhaps not as laugh out loud fun, but I still really enjoyed it.
This story is split between Astrid’s and Mark’s points of view. Astrid’s is also split between present day and her past. I really liked Astrid and learning more about how she became an assassin and why she chose to leave that life was very interesting. She is a fierce example of a survivor. She is a bit hot tempered and rash at times, but I also totally got why she would act before thinking. Her journey in this book was great and I loved that she was finally able to open up to the others in the end.
Although I liked Mark’s part of this journey, I wasn’t very happy with his decisions concerning his atonement with another former assassin. I kept hoping for a better outcome from their interactions. I really enjoyed the lengths he went through to keep from killing in this one, including fighting another assassin and leaving him alive in the end. Mark’s growth as a character in this one was more subtle, but still very important.
The writing and the pacing were once again perfect for this thriller. I loved how Mark and Booker are out to rescue Astrid, but she pretty much rescued herself. The setting of the remote snake infested black site prison was well done and it felt creepy and scary all at the same time. The dialogue is snarky and well done. This was a book that I just raced through because I needed to know what was going to happen next.
If you enjoy thrillers, especially those about former killers who are trying to be better people than this is a series you need to give a chance. I love the morally gray characters, the 12 step program that they follow and all of the ways they find to not kill someone. This is also a rather funny book, if you like dark humor. You could read this as a standalone, but I encourage you to start with the first book.

This book has an unusual pretext. There is a group of very dangerous assassins who have vowed to never kill again. They have meetings and count the days since their last kills. When a colleague of theirs disappears they decide to try and rescue her, but no killing allowed. The book is filled with suspense from the first page and has some clever dialogue. Thank you to net galley for an advanced readers copy.

Thanks to NetGalley and Penguin Random House for sending me an ARC of The Medusa Protocol in exchange for an honest review.
The Goodreads description of this book tells you everything you need to know about the plot, so I’ll jump directly to my thoughts.
The Medusa Protocol takes place about a year and a half after the end of the first book in this series, Assassins Anonymous. All the characters who survived that story are back here, with several new ones thrown in. The story moves between three timelines: Mark’s present-day perspective, as he tries to find Astrid; Astrid’s present-day perspective, as she tries to understand and escape her predicament; and Astrid’s past, as we see various turning points that might explain who is holding her prisoner and why.
As with Assassins Anonymous, The Medusa Protocol works on a number of levels. There’s the mystery of what’s happening to Astrid and why. There are the thriller aspects of the attempts to free her. But mostly the story works because both Mark and Astrid are engaging characters, and the more you learn of Astrid’s backstory, the more you care about what happens to her character. I’m already looking forward to the next book in the series. Recommended.

Story is told from the POV of Astrid and Mark and is the sequel to Assassins Anonymous. I didn’t read the first book so aware I missed important things but got a good idea about this AA Group!
Mark and Astrid as well as several others are all ex-assassins. And they have promised themselves to never kill again. When Astrid, FKA The Angel of Death is a retired assassin has been ‘kill free’ for several but has stopped showing up to Assassins Anonymous- probably means one of two things: Astrid has "slipped" and gone back to killing or has been killed. Only her sponsor Mark, FKA ‘Pale Horse’, had been deadliest killer in the world, holds out that she is okay. In fact, Mark keeps saving a chair for her in hopes that she will show up.
Then, during a meeting, the group gets a pizza delivery. The group immediately wonders if there is another psychopath out there who actually likes olives on their pizza, or is Astrid trying to send Mark a message?
(This made me laugh as I just finished a Young Adult and ta Pizza with olives was order – One of them was indeed was close to being
psychopath!)
Story actually started when Astrid wakes up in the cell on a remote island. Her captures are looking for a vital clue from her past.
Mark and Booker - a fellow AA comrade - set out to rescue Astrid from a South American prison located on’ Snake Island’ a restricted island off the coast of Brazil covered in poisonous snakes, and mean armed guards barbed-wire fences and security cameras,
Booker pointed out that prisons are designed to keep prisoners from breaking out not breaking in!
But first they need to secure some nonfatal weapons and a sitter for Mark’s cat. Yes glad there is some humor in this story – perhaps but you knew that when you found out this story is about a group in ‘Assassins Anonymous’. But there is sure nasty things going on.
I want to thank NetGalley and Penguin Group Putnam/J.P. Putnam’s Sons for this adventurous story.
Publishing Release Date scheduled for June 24, 2025.

The idea that there's a 12-step program for assassins is kind of wonderful and leads to all sorts of ways that "making an amends" could go. Here, we have Astrid, taken to a remote island and tortured (sort of) for information she has and the rest of her recovery group trying to rescue her. No surprises about how it goes!
There are several scenes with Astrid or Mark making choices about weapons or how they're fighting to not actually kill the other person because, you know, they're in recovery. That added something different and a little unexpected to what's a sort of standard action book. The decisions they make and their reasons are worth the read.
I'm looking forward to seeing if Book 3 follows this plotline or if another member of the group is the focus. There are so many possibilities!

The Medusa Protocol is the second book of the Assassins Anonymous series and is every bit as good as the first. This book centers on Astrid, who is kidnapped, and the rest of the group trying to rescue her. Of course, they are again all hampered by not wanting to actually kill anyone. There are a few non-group returning characters and some new ones, along with continuing storylines, so it’s best to read the first book before starting this one. These are clever books and genuinely fun to read.
My copy of this book was provided by the publisher via NetGalley in exchange for an honest review. My thanks to the author, the publisher, and NetGalley for the opportunity to read and review it.

This is #2 in the series and focuses primarily on Astrid. We got a more in-depth look at her past and her recovery. It had the same group of characters and the same humor from the first book. I enjoyed reading it!

I'm not fully convinced that there is are a large number of professional killers who would choose to leave that life in a manner such that others will know about it.

The Medusa Protocol is a sequel to Assassin's Anonymous. It can be read without reading the first book as I did. But to fully enjoy this book I feel that it would be best to read the AA first. I felt left behind since I did not know the background of the characters,
An intriguing concept of a group of assassins that form a group based on the outlines of Alcoholics Anonymous. They have all been deadly killers and are now committed to changing their lives. They support and mentor each other as they perform the steps to achieve a life without destruction.
When one of the members disappears without a trace the group bands together to find their missing friend. There is no doubt in their minds that they will find her, but can they rescue her without breaking the vow they took not to kill again.
A fast-paced thriller that will keep you interested until the end. A definite read for those who love action paced novels.
Thank you Negalley, the publisher and the author for the opportunity to read an advanced copy of this novel.

Thanks to the publisher and NetGalley for this uncorrected proof to review.
As soon as I saw Rob Hart had another book coming out, I rushed to find out as much as I could. The Medusa Protocol is a sequel to Assassin's Anonymous, which you should definitely read before reading this book as quite a lot of the first book comes into play. If you enjoyed the first book, picking up this one is a no-brainer.
In this sequel we learn more about Astrid, her past, and her recovery, and it is a wild adventure. Like the first book, this one deals with some pretty heavy themes surrounding loss, power, making mistakes, and recovery. There are two point of view characters, offering us a glimpse at Mark's current life and his continued recovery, but the focus is primarily on Astrid.
Fans of mysteries, thrillers, and prison escapes will find plenty to love in this book, as will those who like something a little deeper with questions about what we do with our lives and who that helps us become. I highly recommend this book.
If you've already read it and enjoyed it, check out Rob Hart's The Paradox Hotel and The Warehouse too, because I've loved everything of his that I've read.
