“John Casey has accomplished the nearly impossible—to follow up his singular, thrilling, and insightful debut novel with an even more impressive sequel. As someone who knows quite a 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

In DEVOLUTION: Book One of The Devolution Trilogy, former Special Operations pilot Michael Dolan is lured from his desk at the Pentagon by a CIA counterterror unit to assist in a vital clandestine operation in Paris, France, a place from his past marked by tragedy. As the perilous mission unfolds, he comes to realize that of all the demons he must prevail against, the most terrible are from within. Ultimately, the beyond-black efforts of his team succeed, though with mixed results for Dolan personally.

The story continues in EVOLUTION. Two years have passed since the dramatic conclusion of Operation EXCISE. Michael 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…

JOHN CASEY is a National Book Award and Pushcart Prize-nominated novelist and poet from New Hampshire.
