Desperate for a future that doesn't end at the Last Gate, Ember and Evadne have abandoned their path through the Moores and fled aboard a skye pirate ship. But fate will not surrender them so easily and they are pursued by darkness, even across the skies. As the Knight's power continues to grow, the cost of their freedom might be the Realm's destruction. The girls must make what feels like an impossible choice—to escape in search of the happy ending denied to them by prophecy, or to embrace what they're meant to be. Will their hearts compel them to return and save the very Realm that has taken everything from them? Meanwhile, the menacing shadows around Jeremiah's compound have only deepened, and Faye and Ronan are locked in a stalemate. The situation is more complicated than Faye first thought. And so are her feelings about Ronan. But time is running out and she must decide. Will she surrender her anger and join forces with Ronan to help him save his sister from Jeremiah? Or will she let the hatred fester and watch as Jeremiah's madness destroys them both? Faye's only chance to save herself, and her father, may hang in the balance.
