Everyone thinks 10-year-old Thomas Trew is weird: neighbours, other kids, even his own dad.

Thomas doesn't really mind. It's been like that ever since he can remember. Then one day there's a dwarf in his house, and his life changes forever.

Thomas is summoned to the Hidden World -- a magical place responsible for dreams, music, and imagination in the Obvious World (the human world).

Extraordinary adventures await Thomas and his shape-shifter friends, caught up in the unpredictable rivalries between the different races of this world.

He soon discovers his true talents and emerges as a Rymer, able to take his place as a link between the worlds of imagination and magic and the everyday.

Thomas comes to understand both, and his 'weirdness' becomes greatness indeed.
