I burned through “The Conscripted Extremist” by A. Marc Ross on a cross-country flight. It’s a page turner, with plenty of twists, turns, good spies, bad spies, and spies who may be good or may be bad. And lots of didn’t-see-that-comin’ moments. But it’s also a story of love and friendship set in my beloved Manhattan. If you’re a thinking reader who enjoys trying to unravel a mystery, you won’t be disappointed.
