Dean Koontz's Frankenstein is the collective title of five novels co-written by Dean Koontz. Though technically of the mystery or thriller genres, the novels also feature the trappings of horror, fantasy, and science fiction. A fourth novel, Lost Souls, was published in May 2010, and a fifth, The Dead Town, was released on May 24, 2011. Although it was originally announced that the fourth, fifth and sixth novels would form a second trilogy, the cover for The Dead Town states it is the final volume.
