Anna is the daughter of one of the High Fae kings and second-in-line to inherit the throne. Unfortunately, her limited magic abilities means she's destined for a long, lonely life among her magical fae peers. Her father sends her away to live far from the only home she's ever known in the hope that she might find her place in the fae world.

Fate, however, brings her together with Finn Cullen, a human with a quick wit and a dark past. Trouble finds them and binds them together in a pact known only in legends. Now their future is filled with terrifying enemies and dark places unknown, but the bright light of hope leads them ever onward.
