David Levithan is an American young-adult fiction editor and award-winning author. His first book, Boy Meets Boy, was published in 2003. He has written numerous works featuring strong male gay characters, most notably Boy Meets Boy and Nick and Norah's Infinite Playlist.
At 19, Levithan received an internship at Scholastic Corporation where he began working on the The Baby-sitters Club series. Levithan still works for Scholastic as an editorial director. Levithan is also the founding editor of PUSH, a young-adult imprint of Scholastic Press focusing on new voices and new authors. PUSH publishes edgier material for young adults and is where Patricia McCormick got her start with 2002's Cut.
In an interview with Barnes & Noble, Levithan claimed that he learned how to write books that were both funny and touching from Judith Viorst's Alexander and the Terrible, Horrible, No Good, Very Bad Day. He continues to work as both a writer and editor saying, "I love editing just as much, if not more than writing". Levithan's first collaboration with author Rachel Cohn, 2006's Nick and Norah's Infinite Playlist was adapted for the big screen in 2008, and his novel, Love is the Higher Law, was published in August 2009 by Knopf Books for Young Readers.
