Here is how Dark Horse Comics describes the novel:
He may be red. He may be horned. He may be misunderstood. But when you need the job done right, it's time to call Hellboy. Along with his expanding team in the Bureau for Paranormal Research and Defense - pyrotechnic girlfriend Liz Sherman, aquatic empathy Abe Sapien, and protoplasmic mystic Johann - the BPRD will travel between the surface strata and the unseen magical one, where creatures of fantasy become corporeal. And Hellboy, a creature of two worlds who's accepted by neither, must choose between the life he knows and an unknown destiny that beckons him.
Robert Greenberger is best known for his Star Trek: The Next Generation novelizations, including A Time to Love and A Time to Hate. He has also written novels set in the Predator and Godzilla universes.
Hellboy II: The Golden Army comes to theatres July 11, 2008.
