Two enemies must overcome their first impressions of each other after a hot summer night in the sheets, risking their closely guarded hearts for a shot at love in the final book of the Invincible Summer series by Carina Gaskell.

Layla hates Lucky. Lucky hates Layla. But when they spend a hot summer night tangled up in sheets, everything they've come to know about life, love, and each other, is put into question.

Three dates. That's all Lucky asks for. Three dates is a fair enough chance to see where it can go between them. But Layla keeps her heart closely guarded, and Lucky is running out of time and ways to scale her sky-high brick walls.

With summer drawing to a close, a decision must be made before Lucky leaves Dalisay—and Layla—for good. Is this just a fling, or could it be something more?
