Again?

Carla is spending yet another summer on the godforsaken island she always has to spend her summer on. Only, this time there's someone at her own age on the island. Someone really attractive.
Two and a half years later she's in the busy city, trying to recreate herself after a terrible heartbreak. But it isn't always that easy, especially not when certain people from her past shows up again. What really happened that summer that changed her life? What was it that changed her life? Does things really happen for a reason? Or is it just the chance?
