They want her on the throne. But the closer she gets, the deadlier her magic becomes. And an ancient power gets closer to breaking free…

Wren's gone from being a parentless girl with a free life in the forest, to the daughter of the lost queen of Asteroth. Trapped in the capital, she's surrounded by people who would kill her if they discovered her shadow magic. And the strength of her dark power is growing out of control…

Though Finn considers Asteroth his home, as the son of the enemy king he has never been fully at ease in the capital. But now, it's torture. Keeping Wren's magic hidden goes against every vow he's ever taken. But whenever they're apart, the strange ache in his chest becomes unbearable.

Snatching moments together in quiet corners of the castle, the solace Wren and Finn find in each other is bittersweet. The Regent's Council want to keep the control they've held since the queen was lost – but their plan to use Wren as a puppet could see the kingdom torn apart by her dark power. And with the enemy preparing to invade, danger is growing outside the city walls too…

With their loyalty to each other tested at every turn, can Finn and Wren find safety in their love? And can Wren escape from the power play inside the castle and save the kingdom: even if it's from herself?
