Sarah, from sunny Brisbane, Australia, tries to lead a normal life of university, work and spending time with friends. This routine gets thrown out of order when she meets Caitlin, a little girl who looks around seven, dressed in pink, and her companion animal Wuzzle, a giant brown bear-like creature with razor sharp teeth. Sarah learns she is a Phase Walker, with the rare ability to travel between planes and is soon caught up in a war of magic between angels and demons that spans across worlds. Torn between her new boyfriend on Earth and her new life in the Phase, Sarah has some difficult choices to make.
