The Dark Dreamweaver — Nick Ruth

Eleven-year-old David is suffering from nightmares. Over and over again, he dreams about a strange, bear-like man with black eyes. He's not the only one; an epidemic of nightmares seems to have infected the Earth. David takes matters into his own hands and embarks on an adventure to Remin, a land powered by dreams. Aided by a caterpillar wizard, a jellyfish-man, two wise-cracking water serpents, and several other unusual characters, he sets out to find and confront the evil wizard who is causing the nightmares. The challenges that he encounters will require all of his intelligence, his courage, and most of all, his imagination.
