Abby’s senior year of high school is textbook perfect: She has a handsome and attentive boyfriend, good friends, good grades, and plans to attend college next year. But when she meets Dante Alexander, a foreign-exchange student from Italy, her life suddenly takes a different turn. He’s mysterious, and interesting, and unlike anyone she’s ever met before. Abby can’t deny the growing attraction she feels for him. Nor can she deny the unusual things that seem to happen when Dante is around. Time behaves differently when they are together — traveling too fast or too slow or sometimes seeming to stop altogether. The Hourglass Door When the band Zero Hour performs at the local hangout, Abby realizes that there’s something dangerous about the lead singer, Zo, and his band mates, Tony and V. Oddly, the three of them are also from Italy and have a strange relationship to Dante. They also hold a bizarre influence over their audience when performing. And Abby’s best friend, Valerie, is caught in their snare. The Golden Spiral The hourglass door has closed behind Dante, sending him back in time to hunt down Zo, Tony, and V. Abby knows that Dante, as a Master of Time, is the only one who can stop them from destroying time itself. She also knows that he will need her help. But almost immediately, things start to change, and Abby’s worst fears are realized when Zo begins targeting her past specifically. The Forgotten Locket When Abby stepped through the hourglass door, it was in full faith that she could find a way to repair the damage to the river of time and restore what she had lost. It was a desperate chance that seemed worth taking. But Zo had other plans. 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.
