HarperCollins to Publish New Novels by James Frey James Frey is once again venturing into young-adult literature with a new series, "Endgame," that has been acquired by HarperCollins, the publisher said on Tuesday. In an unusual twist, HarperCollins said "Endgame" would include three novels, nine digital novellas and multimedia elements such as YouTube videos, interactive games and puzzles, and social media. Google's Niantic Labs is one of the partners in the project. Mr. Frey, whose embellishments in his memoir "A Million Little Pieces" earned him a public rebuke on "Oprah" in 2006, has spent the last several years writing for younger readers and working on his own media and production company, Full Fathom Five. In 2009, HarperCollins bought the rights to "I Am Number Four," a young-adult novel by Mr. Frey. Deadline Hollywood reported on Friday that 20th Century Fox paid close to $2 million for the film rights to "Endgame." HarperCollins UK bought the rights to publish the books in Britain. Mr. Frey was represented by Eric Simonoff, a literary agent. The first book, "Endgame: The Calling," will be released on Oct. 7.
