Guillermo del Toro, who’s directed the last two Hellboy films and is about to begin work on two Hobbit films (see “del Toro Hobbit Deal”), will co-write a trilogy of vampire novels with crime author Chuck Hogan.  The first, The Strain, will be released next summer from HarperCollins imprint William Morrow.  The three books will reveal progressively more information about an ancient vampiric race that originated in Old Testament times.
