Author Don Winslow has signed a new two-book deal with HarperCollins’ William Morrow imprint, the publisher announced on Thursday. The prolific crime author behind such bestsellers like Savages and The Power of the Dog is known for imbuing his southern drug narratives with extensive knowledge and reporting. The first of the two books, due out in summer 2017, is being kept under wraps for now, but the second will be the third part of a trilogy about the war on drugs, started in The Power of the Dog and last year’s bestselling The Cartel.
