New York Times bestsellers P.C. Cast and Kristin Cast return with the astonishing conclusion to their new duology set in a dark and magickal world filled with incredible danger and irresistible romance.

Wren Nightingale wasn’t supposed to have any elemental powers. Since becoming Moonstruck on her eighteenth birthday, Wren has found herself thrust into a world filled with deception, danger, and murder. Uncovering that their magick was fractured and limited when the original Moonstruck ritual was broken by Selene, Wren is determined to find a way to join the magicks of the elder, the mother, and the maiden. But the Elementals are split into two factions—some want the ritual completed and their freedom—and others are terrified of change. So terrified that they’re willing to end Wren before she can reach the center of the island where the ritual Selene ruined can be completed.

Between his overbearing father’s arrival, Rottingham delegating him more and more responsibility, and Celeste taking a special interest in him, Lee Young has been struggling to find his own path. As much as Lee wants to take his place in the Moonstruck hierarchy, not everything he’s being told adds up—like, no matter what Celeste says, he knows something’s not right at the Academia de la Luna. He thinks if he can talk some sense into Wren and get her to return to the Academia, that everything will turn out alright.

As Wren and Lee both battle for what they believe is right, they’ll have to uncover who their true allies are…and if they’re even on the same side of this magickal fight.
