Belief is a powerful magic.

Valerie Diaz has a power that she can't contain, and it's killing her. Bounced between foster homes and the streets, she only has time to concentrate on staying alive. But a visit from the imaginary friend of her childhood opens a world of possibilities, including a new life half a universe away on a planet that is bursting with magic.

The Society of Imaginary Friends follows Valerie on a journey that straddles two worlds. In order to survive, she must travel many light years away to a realm where anything is possible. On the Globe, imaginary friends come to life, the last of the unicorns rules the realm, and magic seeps from the pores of all the Conjurors who live there. But choosing to embrace her potential will set Valerie on a treacherous course – one filled with true love, adventure and perilous danger.
