Kristy O'Neal gave up her dream job as a park ranger at Shiloh National Military Park to get married and move away. When she's left at the altar, she returns to the park to find her old position has already been filled. She accepts a seasonal position even though it is a step back, career-wise. Working alongside Ace Kennedy (the man who has her old job) is almost more than Kristy can handle. Throw in a matchmaking mother and friends who think she should put herself back in the dating game, and Kristy is nearly at her wits' end. She sees the past as a battlefield of failed relationships and isn't sure she's ready to risk her heart again. For Ace Kennedy, history offers proof that true love exists. With stories from the park's rich history in his arsenal, he begins the battle to win Kristy's heart. But when Kristy learns he's keeping secrets from her, her skepticism of love seems justified. Can she risk her heart on the battlefield of love one more time or will Ace lose Kristy forever?
