The Ascendant: A Thriller
By Drew Chapman
(Simon & Schuster, $25)

In this fast-paced debut novel by screenwriter Drew Chapman, an unlikely hero is recruited by the U.S. military to save our nation against a multipronged war that includes cyber attacks, crushing real estate deals and Treasury bond sell-offs. Wall Street trader Garrett Reilly is hardly patriotic, but his gift for detecting patterns makes him the most wanted man on Earth. Reilly’s reluctance to help fight off these attacks adds to the edginess of this page-turner that seems frighteningly realistic as Chapman uncovers new parameters for how war might be waged in our brave new world.
