The finale in the contemporary fantasy Only a Monster trilogy from Vanessa Len—which New York Times bestselling authors Holly Black, Chloe Gong, and Stephanie Garber called “delightful," "captivating,” and “unputdownable”—will take Joan into the darkest timeline in the monster world, as she fights to restore the world she remembers.

Joan has failed to stop Eleanor.

Now restored, the thirteenth family rules ruthlessly over a new London in which monsters live openly among humans, preying on them and subjugating them.

Only Joan and her friends Aaron and Nick remember that there was once a better timeline. Now, as they negotiate their fractured pasts and face wrenching emotional decisions, they must fight to survive the new world and fix the broken timeline.

But how will they defeat a whole family of monsters with power over time itself?

The unstoppable love and high stakes of Divine Rivals meets the intricate worldbuilding and propulsive thrills of This Savage Song in this high-octane, cross-genre finale to the Only a Monster trilogy—where a breathless race against time and an all-knowing enemy is the only chance for Joan, Aaron, and Nick to restore the world they love.
