Joan has failed to stop Eleanor and her monstrous plan.

Eleanor now rules ruthlessly over a new London, in which monsters live openly among humans, preying on them and subjugating them.

Only Joan, 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 Rebecca Ross's Divine Rivals meets the thrills of Chloe Gong's These Violent Delights in this high-octane, cross-genre finale to the Only a Monster trilogy - where a race against time and an all-knowing enemy is the only chance for Joan, Aaron, and Nick to restore the world they love.
