Emma wandered down to the edge of the tropical lake, toes sinking into warm sand. Three guys were already there - one playing a ukulele, one floating on a giant flamingo, and one handing out pineapple slices. She joined them without a second thought. They swam, joked, and raced across the water on paddleboards. Laughing under palm trees, Isla thought. This is what summer should always feel like.
