The photograph, taped to the breakroom fridge, drew Maya to it. It was a picture of Camp Timberline, the very camp where she had first learned to swim. She felt a familiar thrill.

"Camp Timberline?" she asked, turning to face Liam, who was making coffee. "I used to go there every summer!" He chuckled, and Maya realized she was smiling, a genuine, unguarded smile that she hadn't realized was missing.
