Tyrtle Island: Boo and the Bullkats:

Jesse Quinn’s life is about to change in a way he never expected. An image of hot flowing lava flashes through his mind. Spooky yellow eyes and ghost-white horns hover over him. The deadly bullkats, once thought to be extinct, are now roaming around Tyrtle Island … and in his dreams.
This is no ordinary dream about an adventure on any ordinary island. It’s an island dream with Jesse’s cat named Boo, his Uncle Tinman and his island friends. Dreams are nothing unusual, but Jesse never imagined a dream experienced through the eyes of a cat. Not just any cat, Jesse lives this dream adventure through the mind of Boo.
Jesse quickly finds out that keeping Boo out of trouble is the least of his worries … in real life … and in his dreams. Professor Katnip sends Jesse, Boo and their friends on a quest, but someone or something is trying to stop them. On their journey across the island they battle bullkats, belly birds and big-toed buggers. Unknown to them, this adventure leads them deep into the lava monster’s abyss. Tyrtle Island’s ancient history and the Island’s future are at stake. Once they enter the lava monster’s mouth, there is no turning back.
