In book after book, this astonishingly talented (and astonishingly young) author approaches genres we might dismiss as shopworn - the campus mystery, the family drama, the out-of-the-past whodunit - and with a flourish, whips them into spectacular new shapes. And in The Enigma of Room 622 - as you'll learn early on, there is no Room 622 - Dicker salutes Agatha Christie even as he drops the reader through one trapdoor into another, so that by the end, we doubt we've ever read another novel quite like it. (We haven't.) Fans of Ruth Ware and Lucy Foley will hug this book in between chapters; the many readers who love Anthony Horowitz's mysteries will celebrate. And me? I'll be reading it again A.J. Finn
