"It's happening again, Aidan. We didn't stop it, after all." As an elemental, Aidan Brook holds the power of water at her fingertips. A descendant of the earth's oldest magic, she can cause tides to ebb and flow, put out house fires without calling 911, and give anyone who's annoying her an impromptu shower. But even her magic has its limits. After it fails her one terrible night, she hides from the world and everyone she once loved, trying to escape the memories that haunt her. Ten years later, her exile is brought to an abrupt end when her former best friend appears on her front porch. An elemental killer is once again murdering her friends, and she must return to the scene of her own crimes. Lake Tahoe proves more than she bargained for. Between a sadistic killer, some clever FBI agents, an annoyingly attractive landlord, and way too many new roommates, she has a pretty full plate. Add in a past she's desperate to escape and her own uncontrollable powers, and Aidan Brook is having a very, very bad month.

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.
