Carl and Marianne were high school sweethearts, loving the way only teenagers can—with no thought to logic or pride, just a bone-headed, optimistic frenzy of unicorns and hormones. That was all they needed. Or so Carl thought.

Scared of being stuck in Lake Sackett, Georgia, like so many of her friends—without a real shot at a future or achieving her own dreams—Marianne panicked and bolted to college after stomping Carl’s heart into the high grass. But when she returns to Lake Sackett for the summer with her family after years away, she and Carl are drawn together like moths to a flame. As they rekindle their old romance and remember what it was like to be in love, they have to wonder: is this, finally, their real chance at happiness?
