Flynn, an extraordinarily good writer, plays her readers with the finesse and delicacy of an expert angler. She wields her unreliable narrators to stunning effect, baffling, disturbing and delighting in turn, practically guaranteeing an immediate reread once her terrifying, wonderful conclusion is reached. . . an early contender for thriller of the year, and an absolute must-read.
