The Devolution Trilogy: Book Two

Two years have passed since the dramatic conclusion of Operation EXCISE. Dolan has moved home to Boston to mend when once again, the Agency comes knocking. Terrorists have launched a bioweapon in the Middle East, thousands are dying of a horrifying virus with no cure, and Dolan is the key to preventing more attacks. Only this time, everything will be done on his terms…

EVOLUTION is book two of a psychological spy thriller series (The Devolution Trilogy). Nominated for five literary awards.

FROM THE AUTHOR:  Fans of Robert Ludlum’s The Bourne Identity will appreciate the internecine struggle and cryptic complexity of the protagonist, Michael Dolan, as will fans of Tom Clancy’s Patriot Games who savor a page-turner about an unlikely spy thrust into adversity, only to emerge the strongest and most capable of them all. 

When I began writing The DEVOLUTION Trilogy I wanted to create a story where the depth and complexity of the main character, Michael Dolan, were just as compelling and important as the plot. As spy thrillers go, this series has everything readers of the genre crave: action, suspense, cliffhangers and mystery. What makes the story so unique (and that much more captivating), however, is Dolan's dark and labyrinthine psychological struggle as he navigates the challenges of his top - secret missions while confronting the demons of his past. 

“John Casey has accomplished the nearly impossible—to follow up his singular, thrilling, and insightful debut novel with an even more impressive sequel. Evolution’s main protagonist, Michael Dolan, is one of the deepest characters I’ve seen in this type of fiction. As someone who knows more than a little bit about the clandestine world, I found Evolution to be a crisp, hard-hitting and realistic yarn that will leave you wanting more.”

• U.S. AMBASSADOR LUIS MORENO spent a major portion of his Foreign Service career assisting in the pursuit of Pablo Escobar and leading implementation of Plan Colombia

"Keeps readers tense and wondering...just as, or even more gripping than its prequel...a riveting story that deserves top billing in any thriller or espionage fiction collection." 

• The MIDWEST BOOK REVIEW

"Evolution is a complex and multifaceted, chilling story of bioterrorism headlined by a remarkable and courageous protagonist! Five stars."

• Readers' Favorite

“Casey’s frank and realistic interplay among the principals draws you into a complicated plot about believable challenges, both in the field and inside the walls of counterintelligence operations. His craftsmanship is evident as the plot progresses until the tension becomes too fervent to put aside.”

• JAMES WHITE, author of Borders in Paradise

“With granular detail of terror networks, spycraft, and deft depictions of the psychological calculations between handler and operative, spy and target, US and foreign governments, Casey’s tale keeps the reader turning the pages!”

• CAROL LaHINES, author of Someday Everything Will All Make Sense

“With strong mechanical and technological precision, Evolution gives readers solid grounding and pulls them through realistic 21st-century action. A strong spy thriller with global and personal stakes”

• Independent Book Review (IBR)

“John Casey has done it again—delivering a page turner that combines spy novel with psychological thriller, an imperfect, unique, and compelling lead, a carefully-crafted storyline, and twists along the way the reader won't see coming!”

• DONNA KOROS STRAMELLA, author of Coffee Killed My Mother
