The novelization of Hellboy II: The Golden Army has been written by Robert Greenberger, and is scheduled for a May 25, 2008 release, according to Comics Continuum.

Here is how Dark Horse Comics describes the novel:

After an ancient truce existing between humankind and the invisible realm of the fantastic is broken, hell on Earth is ready to erupt. A ruthless leader who treads the world above and the one below defies his bloodline and awakens an unstoppable army of creatures. Now, it's up to the planet's toughest, roughest superhero to battle the merciless dictator and his marauders.

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.
