When thirteen-year-old Caley Cross, an orphan with a dark power, is guided by a jumpsuit-wearing mole into another world - Erinath - she finds a place deeply rooted in nature where the people have animal-like powers and she is a Crown Princess -but she soon learns that the most powerful evil being in any world is waiting for her there.

Caley Cross has always known she's not a 'normal' thirteen-year-old (her ability to create zombie animals was her first clue). Still, she never expected to be whisked off to a faraway world - Erinath - where she is Crown Princess and people have 'baests' that live inside them, giving them fantastic, animal-like powers. Which would be cool, except that Caley's baest turns out to be an ancient monster that can swallow planets. Despite this, Caley manages to make the first friends of her life, Neive Olander and Kipley Gorsebrooke.

They help her navigate the Erinath Academy, where students train to compete in the annual - and deadly -Equidium contest, flying giant, dragonfly-like orocs. But to add to her usual (bad) luck, an evil 'Watcher' known as Olpheist is seeking her, anxious to retrieve something that will make him immortal. The first in an epic fantasy series from Jeff Rosen that will keep readers laughing and on the edge of their seats.
