What are the Chances - Love in Vacationland, #2

Colette had zero intention of ever going back to her tiny hometown in Maine, until her friend Farrah proposes a month-long vacation-and Farrah is a hard person to say no to. All Collette needs to do is keep her head down and avoid as many people as possible. It's all going well until she runs into her high school ex's little sister, Quinn, who isn't so little anymore. Even though Colette has an instant attraction to her, where would it even go? Quinn is settled in Castleton and Colette is only there for a few weeks.
Quinn can't believe that Colette is back in town. She'd had the biggest crush on her older sister's girlfriend back in the day and now they're both grown, and Colette looks better than ever. She can't believe it when Colette shows interest in her and they end up falling into bed together, but Colette insists it's a one-time thing and will not be repeated. Except that it happens again. And again. And again.
