Hidden (Firelight, Bk. 3)

A dangerous journey.
Shattered bonds.
Undying passion.

Jacinda was supposed to marry Cassian, the prince of her pride, but instead she defied all the rules and fell in love with Will--a human and, worse, a hunter. Their forbidden romance led to the capture of Cassian's sister, Miram. Weighed down by guilt, Jacinda ventures deep into the heart of enemy territory to rescue her, posing as a prisoner herself. Only once she assumes that disguise, things quickly spiral out of control. Even if Will and Cassian can carry out their part of the plan, there's no guarantee they'll all make it out alive. But what Jacinda never could have foreseen is that escaping would be only the beginning. . . .

Loyalties are tested and sacrifices made in the explosive conclusion to Sophie Jordan's Firelight trilogy.
