Under the of the world's finest theme park lies a secret which could alter the course of human history.

Twelve-year-old Mike, a misfit genius with a terrible secret to hide, takes refuge behind the scenes of Dreamworld, a futuristic theme park where hope exists as it does nowhere else. Annie, a midget old enough to be Mike's mother, has lived in Dreamworld for 13 years without revealing her presence to visitors or staff. She takes Mike in hand, and they settle down to a long, happy life together...until they discover that the trolls who maintain Dreamworld are multiplying at an alarming rate without explanation. As the trolls continue to multiply, they must discover why, or it could mean the end of Dreamworld-and the real world.

Knotted in conflict and turmoil, what was a wonderful, carefree place becomes a battleground on which Earth's future is at stake. Only Mike and Annie, two unconventional heroes, can save it.
