Guarding souls doesn't come with a handbook. Piper Laurel may be the Seekin of legend, but she's still learning the subtleties of her gift. She's also busy playing house with her true love, preparing for the birth of their son, and, oh yes, leading a rebellion. No realm is safe with the evil immortal Anik's sinister plot to abduct innocent children still in play. Now fully awakened, Piper accesses the vast knowledge reaped by her past incarnations. But this knowledge comes at a cost. The Laurel curse rages within her. A curse prophesied to end with her unborn son if he chooses correctly.

He may choose light and unite the realms; or he may choose darkness and unleash unparalleled destruction. The first cry of life seals his chosen fate. To protect her son, Piper enters forbidden realms hunting for enchanted talismans. But another hunt is on; a hunt for her heart- preferably in a jar. Eira has also fully awakened, and Anik's co-conspirator won't rest until she's destroyed everyone Piper holds dear, starting with the precious child. With time running out, Piper learns just how much heartbreak a mother can bear. As darkness descends, she must choose: save millions of souls or just one.
