Amelia Clearwater, a werewolf-witch hybrid, begins experiencing vivid dreams where she lives another life — one where she’s fleeing with her newborn child from unseen enemies. As the dreams intensify, she realizes she’s not dreaming — she’s crossing between realities. Her child in that other world isn’t ordinary — he is a Realm Jumper, born with the power to open portals between dimensions. But because he’s the last one left, every dark force from every realm wants to claim or destroy him.
