"Men like pie." Who would know the truth behind those words better than Elaina Brady's mother Maria? Months after she showed her teenage daughter how to bake perfect pie and hours after offering that culinary wisdom, Maria abandons Elaina, her sister Dee Dee and their father Walt. All it took was a lingering, lusty look from a Missoula trucker who stopped by their family's diner and ordered a slice of lemon meringue. Maria hitches a ride west with him, and with that impulsive decision, sixteen-year-old Elaina loses her mother and gains a job baking pies at the diner.

A decade after Maria's departure, Elaina is still working at The Terminal Diner, just around the bend from an upstate New York airport. Her humdrum life is defined by pie-baking routine. Elaina realizes painfully that all she still knows about the opposite sex is summed up in the three last words her mother spoke to her. Then one deceivingly beautiful morning in September 2001, horrifying acts committed by terrorists a hundred miles away upset her world, bringing new influences into her life and inspiring her to be like her mother-impulsive. Will Elaina survive the consequences of her actions?
