They have been protecting the world and watching the youngest among them grow up. But for this family, peace will never last. When seventeen year old Lili Wibberly accidentally activates mysterious magic, she and her girlfriend, Eternity, find themselves falling through a mirror and into an alternate universe that has experienced events very differently then their world has.

But when things go wrong and worlds collide, Lili and Eternity must gather their family and fight to save everything they love. And Sierra is on a mission of her own, one to kill the Dire Magnus. The question is, why is she so determined to complete this mission, and just how is she connected to the Wibberlys?
