The Unwilling - Kelly Braffet (Barrier Lands Book 1)

She has no name and no history, but she has a power greater than the Empire has ever known.

Judah is an orphaned girl with a secret gift, born at the gates of Highfall castle. Raised alongside Gavin, heir to Lord Elban's empire, the two share a bond - one that is key to Judah's survival and destined to be Judah's undoing. Elban - as mighty as he is cruel and greedy - plans to use Judah as a pawn to amass greater control.

He will stop at nothing to get what he wants. But beyond the castle walls, a magus, a healer with his own powerful force, has arrived from the provinces. He, too, has designs on the realm, and at the heart of his plans lies Judah...

The girl who started life with no name and no history will soon discover her own strength. She does not have to be given power: she can just take it.
