Ivy has always been able to see clocks over everyone's heads, counting down how long before they will die. Her own will hit the zero hour before she even graduates high school. She struggles with her deep love for on-again, off-again boyfriend Myers Patripski. And she struggles to cope with the murder of her best friend, Vanessa Donovan, another life she couldn't save. Then more girls start disappearing. The clock is always ticking. And Ivy's only hope is to expose the truth before it runs out completely.
