About this book

Book Summary

Welcome back to Assassins Anonymous, the only twelve-step group where joining can be deadly.

When Astrid, known in her assassin days as Azrael, stopped showing up to Assassins Anonymous, the group assumed her past had caught up with her. Only her sponsor Mark, formerly the deadliest killer in the world, holds out hope that she's okay. Then, during a meeting, the group gets a sign, or rather, a pizza delivery. Is there another psychopath out there who actually likes olives on their pizza, or is Astrid trying to send Mark a message?

Meanwhile, Astrid wakes up in the cell of a black site prison, on a remote island. A doctor subjects her to mysterious experiments, plumbing the depths of her memory and looking for a vital clue from her past. She'll do anything to escape, except…killing anyone. Hmm. Turns out it's not easy to blow this joint without blowing anything, or anyone up.

Media Reviews

"Hart triumphs with this deliriously enjoyable sequel to Assassins Anonymous...He keeps the tone sharp and the intensity high. Fans of Jeff Lindsay and Jeffery Deaver will delight in this series' effortless mix of wit and brutality." —Publishers Weekly (starred review)

"Terrific...This new entry in Hart's solid series is just as good as the first, with thrills, humor, and an ingenious plot. The cast of characters continues to grow, and each is fleshed out enough to lead their own book. Readers should get on the Assassins Anonymous wagon." —Library Journal (starred review)

"[C]heeky, swiftly paced...[T]he stakes are human, the worldbuilding is fun, and the vibrant supporting cast is stocked with spinoff-worthy personalities. Hart brings the heart in this entertaining tale of redemption, sacrifice, and found family." —Kirkus Reviews

"High octane and irresistible, this page-turner is not only breathtakingly smart, but heartbreakingly unique. Completely cinematic, constantly entertaining, and written with Hart's signature dark wit, The Medusa Protocol offers non-stop suspense with the highest of stakes. Do not miss this!" —Hank Phillippi Ryan, USA Today bestselling author of One Wrong Word

"The Medusa Protocol is an exhilarating, pulse-pounding sequel to Assassins Anonymous that expands the world while standing on its own as a startlingly original thriller. Not to be missed." —S.A. Cosby, New York Times bestselling author of All the Sinners Bleed
