Iron Bound

Raine Warren, unwilling heir to the Whitefall family of the Winter Court, might have lived long enough to claim the magic she inherited, but there are others who'd like to make sure she can never use it again.
With the Summer Court dangerously close to discovering her deadly secret, her only option to avoid a trial for murder is to ally with the same family who nearly killed her. Her task: find out how her all-powerful faerie mother met her mysterious death, or forfeit her life.
Even with the help of her best friend, Viola, and a certain unreliable thief, her quest seems insurmountable. As the borderlands are threatened by a dark force, Raine finds herself caught up in a conspiracy that puts her and the people she loves in the centre of a confrontation between Faerie and their deadliest enemy. If she lives long enough to learn the truth, exile and death are the least of her worries.
