When Ben's girlfriend, Marly, dies, he feels his life is over and the prospect of Valentine's Day without her fills him with bitterness. But then Marly arrives - or at least, her ghost does - along with three other spirits. Now Ben must take a journey through Valentines past, present and future - and what he learns will change him forever. David Levithan is master of blending fantasy and romance, and Marly's Ghost has every bit as wonderfully strange and magical as Every Day and Another Day. David is the New York Times best-selling author of Boy Meets Boy and Marly's Ghost. While among his many collaborations are Will Grayson, Will Grayson with Fault in Our Stars author John Green, and Nick and Norah's Infinite Playlist with Rachel Cohn, which became a major film. David's latest collaboration with Rachel, The Twelve Days of Dash and Lily, was picked by Zoella for her Book Club with WHSmiths. Tiny Cooper from Will Grayson, Will Grayson, now has his own novel: Hold Me Closer: The Tiny Cooper Story. David is also a highly respected children's book editor, whose list includes many luminaries of children's literature, including Garth Nix, Libba Bray and Suzanne Collins. He lives and works in New York.
