Michael Grant is an American author of middle grade and Young Adult speculative fiction. Before 2008, he wrote almost exclusively with his wife, K. A. Applegate, and all the work was credited exclusively to her. Starting in 2008, however, he wrote entirely on his own, with the exception of Eve and Adam.
Before he and Applegate wrote their own books, they ghostwrote for Sweet Valley Twins, a Spin-Off of the Sweet Valley High series. His books are known for being incredibly dark for books written for kids or teenagers.
