Back cover fluff.
"The book was like no other he had ever seen. The language was alien to the Earth, and the shifting, changing patterns of the illustrations seemed to spell a deadly, dreadful story. The book was a gateway: a transtemporal link point between two worlds. And soon he found himself in that strange other world. It was a weird, alien place of soul-destroying danger, a place in which he had a quest. To survive, he must hunt down the lost daughter of the witch-king, a girl who might be an angel. Or a demon."
