Magic to the Bone (Allie Beckstrom, Book 1)

Devon Monk is casting a spell on the fantasy world...

Using magic means it uses you back, and every spell exacts a price from its user. But some people get out of it by Offloading the cost of magic onto an innocent. Then it’s Allison Beckstrom’s job to identify the spell-caster. Allie would rather live a hand-to-mouth existence than accept the family fortune—and the strings that come with it. But when she finds a boy dying from a magical Offload that has her father’s signature all over it, Allie is thrown back into his world of black magic. And the forces she calls on in her quest for the truth will make her capable of things that some will do anything to control...
