Maddie Fynn is a shy high school junior, cursed with an eerie intuitive ability: she sees a series of unique digits hovering above the foreheads of each person she encounters. Her earliest memories are marked by these numbers, but it takes her father’s premature death for Maddie and her family to realize that these mysterious digits are actually death dates, and just like birthdays, everyone has one. Forced by her alcoholic mother to use her ability to make extra money, Maddie identifies the quickly approaching death date of one client's young son, but because her ability only allows her to see the when and not the how, she’s unable to offer any more insight. When the boy goes missing on that exact date, law enforcement turns to Maddie. Soon, Maddie is entangled in a homicide investigation, and more young people disappear and are later found murdered. A suspect for the investigation, a target for the murderer, and attracting the attentions of a mysterious young admirer who may be connected to it all, Maddie's whole existence is about to be turned upside down. Can she right things before it's too late?

Maddie Fynn knew from the moment she laid eyes on Aiden Faraday that their destinies were intertwined. Born with the unique ability to see the exact date a person will die, Maddie is definitely an expert on destinies. She and Aiden have a deathdate exactly one day apart, far off in the future, sixty years from now. So how could it be that they wouldn't be destined to spend all those years together, especially when they fall madly in love. But when Maddie gives birth to their baby girl, she sees immediately that her daughter's deathdate will be less than a year away, and there seems to be nothing she can do to prevent it. Maddie only knows the when never the how. Still, she couldn't have imagined that concealing that information from Aiden would seal her daughter's fate. Now, their marriage seems irreparably broken as they both blame the other for their daughter's death. This is the story of destined love, and a tragedy that tears that love to pieces. But it's also the story of how those antipodal destinies could be the very thing that brings them back together.
