The only way to rescue the future is to alter the past.

When Abby stepped through the hourglass door, leaving her beloved Dante blind and bleeding on the other side, it was in full faith that she could find a way to repair the damage to the river of time and restore him--as well as her family. It was a desperate chance that seemed worth taking.

Now Abby is trapped in a full-fledged battle for her own mind and life and heart. Even worse, Zo's evil intent reaches beyond simple revenge against her and Dante. The whole world is in danger of collapsing unless Abby can summon her courage and undertake a journey that will lead her beyond the origins of the hourglass door.
