The bank is eroding. The barriers are thinning. And time is running out. The hourglass door has closed behind Dante, sending him back in time to hunt down Zo, Tony, and V. Although giving him up was the hardest test she ever faced, Abby knows that Dante is the only one who can stop the others from destroying time itself. But almost immediately, things start to change, and Abby’s worst fears are realized when Zo begins targeting her past specifically. As Abby’s world fractures around her, she must face a terrible truth: Dante never made it through the door, and he may be lost forever without her help.

So with Dante’s blueprints in hand, she begins construction on a new door, a new time machine that will either save Dante - or doom him. With each new change that ripples into her present, Abby’s life continues to spiral out of control. Her relationships with Jason, Natalie, and even her family are threatened to the breaking point. Zo’s power is greater than Abby ever imagined. Will her love for Dante be enough to turn the tide? This award-winning YA love story is the second in a trilogy.
