Allison Beckstrom's magic has taken its toll on her, physically marking her and erasing her memories-including those of the man she supposedly loves. But lost memories aren't the only things preying on Allie's thoughts. Her late father, the prominent businessman-and sorcerer-Daniel Beckstrom, has somehow channeled himself into her very mind. With the help of the Authority, a secret organization of magic users, she hopes to gain better control over her own abilities-and find a way to deal with her father.
