When a heat wave wrecks Nolan Brooks’ rental car, leaving him stranded in a sleepy little Tennessee town, the goal of spending the summer running his best friend’s beach-side bar begins to flutter out of reach. He’s trying to be responsible and ambitious for the first time in his life, and spending the weekend at a local festival celebrating the migration of the Purple Lacewing butterfly doesn’t fit into those plans.
But he’s stuck for the duration, and making the best of a bad situation doesn’t seem so difficult when a shortage of hotel rooms means he’s spending it with the charming, if mysterious, Gray Ashton. Gray isn’t too fond of tourists, but despite his misgivings it seems he’ll make an exception for Nolan.
When Nolan succumbs to the charms of the town, the butterflies and Gray, he has to re-evaluate what he really wants. But the secrets in Gray’s past and the obligations in Nolan’s future won’t make that any easier than chasing butterflies.
