Nick & Norah's Infinite Playlist

Nick and Norah's Infinite Playlist is the first collaboration novel written by Rachel Cohn and David Levithan. The novel was published in 2006 by Alfred F. Knopf Books for Young Readers. It was adapted into the 2008 feature film Nick & Norah's Infinite Playlist, which both Levithan and Cohn appear in briefly.The novel was in part inspired by Dashiell Hammett's "The Thin Man", though other than the names of the two protagonists bears little resemblance to its inspiration. The chapters from Nick's perspective are written by Levithan while the chapters from Norah's perspective are written by Cohn.
