YA novelist John Green, whose latest effort, The Fault in Our Stars, hit shelves on January 10, has moved from William Morris Endeavor to United Talent Agency for his Hollywood business. Green is now being represented for film by Kassie Evashevski at UTA.

The move comes right as Green's current book is circulating in Hollywood. Not only does Green have a track record among movie execs--a number of his novels have been acquired for film, including 2008's Paper Towns (Dutton) which was optioned by Mandate Pictures and John Malkovich's production company--but many took note when Green successfully drummed up publicity for Fault over the summer. In June he revealed online, to his over 1 million Twitter followers, that he would personally sign every book in the sizeable 150,000-copy first printing Penguin was doing for the book. That move shot Fault to the top of both Amazon's and B&N's pre-order lists.

Fault, Green's fourth novel, which received a starred review from PW, follows a 16-year-old girl fighting cancer who finds unexpected solace and friendship through a church support group. Though the subject material is bleak by Hollywood standards, one insider said many execs may look past that because of Penguin's significant first printing and the strong early buzz about the book itself. Green remains with his literary agent, Jodi Reamer at Writers House.
