Twelve-year-old Thomas doesn't have a dad and so hasn't done much of the "camping-fishing thing." But this year he gets to go on his first week-long summer camp, and it's turning out to be the exciting summer adventure he was dreaming of...that is until he accidentally releases a powerful demon imprisoned in a secret cave behind a waterfall and gets sucked into a dimensional rift...

While lost in an alien world and desperate to return home, Thomas meets a mysterious creature named Arvek who promises to send him back to Earth, but only if Thomas retrieves a magic artifact for him - something called The Crystal of Destiny. To find the crystal, Thomas will have to survive a town overrun by zombies, pass through a forest that turns deadly by night, climb a lava spewing mountain, cross a cursed desert, and sail to a mystical island. But Thomas won't be alone on his journey. At his side is Bruno, a baby giant who will eat just about anything, The Druid, a cloaked vagrant whose wild antics always endanger the group, The "Green Dude," a mumbling shapeshifting blob disguised in a hat and sunglasses, and Darius, a young wizard-warrior sworn to fight an ancient evil.

With such a bizarre band of misfits "helping" Thomas on his quest, it will take more than magic, bravery, and sacrifice to save the cosmos - it will take a miracle.
