Realm Breaker Tome 3
Fate Breaker

The companions are shattered, and the realm hangs in the balance. Taristan and Queen Erida rise triumphant from the battlefield, while Corayne barely escapes with her life ; her Companions left behind to uncertain fates. But not all hope was lost : Corayne stole Taristan's Spindleblade. Without it, Taristan can't rip open any more Spindles. Without it, he can't end the world. Now, from every corner of the realm, the Companions race to rally old allies and seek unexpected new ones, in one final push against darkness.
But Taristan and Erida are all but invincible. With their cruel god, What Waits, on their side, they will sacrifice anything and anyone to his hunger. Everything has come to this : a ragged alliance makes its bravest stand against a ruthless enemy who would consume the realm entire.
