That Crush. That Boy Series, #9

The only thing she was looking for was a summer fling-until he kissed her. When Damon Diamond first laid eyes on Ainsley Archibald at fifteen, he knew it was more than just a crush. But with their four-year age gap and her indifference, he had to keep his feelings at bay. Three years later, everything has changed. Damon's no longer the boy she barely noticed-he's grown into a confident, irresistible man with one goal for the summer: to make Ainsley his.
Ainsley arrives at her uncle's resort in the Ozarks, eager to get back out there after a bad breakup. But the moment she lays eyes on Damon, everything shifts. He's hot, heading to college, and the chemistry between them is undeniable. What starts as harmless flirting, quickly spirals into feelings that neither of them can ignore. Torn between her desire for him and the complications of their age difference, Ainsley must decide if she's ready to risk everything for a summer of love.
Because Damon isn't just after a fling-he wants her heart. Age-gap tension. Heart-pounding kisses. A love story you'll feel in your chest. Although this is book nine in the That Boy series, the trilogy of That Crush / That Girl / That Someday can be read as a standalone series featuring Damon and Ainsley.
