Karen Dionne's debut psychological suspense novel THE MARSH KING'S DAUGHTER became a #1 international bestseller and is now published in 25 languages. Described by The New York Times Book Review as “Subtle, brilliant and mature . . . as good as a thriller can be", it was named a 2018 Michigan Notable Book, took home the Barry and the Crimson Scribe Awards for Best Novel and is in development as a major motion picture. Her next book, The Wicked Sister, is slated for release in August, and international bestselling author Karin Slaughter calls it "massively thrilling and altogether unputdownable".
