Despite the odds, Joan achieved the impossible. She reset the timeline, saved her family - and destroyed the hero, Nick.
But her success has come at a terrible cost.
She alone remembers what happened. Now, Aaron, her hard-won friend - and maybe more - is an enemy, trying to kill her. And Nick, the boy she loved, is a stranger who doesn't even know her name. Only Joan remembers that there is a ruthless and dangerous enemy still out there.
When a deadly attack forces Joan back into the monster world as a fugitive, she finds herself on the run with Nick - as Aaron closes in. As the danger rises - and Nick gets perilously closer to discovering the truth of what Joan did - Joan discovers a secret of her own. One that threatens everyone she loves.
Torn between love and family and monstrous choices, Joan must find a way to re-gather her old allies to face down the deadliest of enemies, and to save the timeline itself.
