Jacob Jacobson grew up with a constant diet of Roger Zelazny, Robert A. Heinlien, Ray Bradbury and Harlan Ellison
(interesting for a young reader).
He also very much enjoyed the works of Tolkien and Brooks.
And yet his first book is a vampire book, full of werewolves and owls.
Good thing his youth had a little room for Dean Koontz and John Saul.
