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."
