Firefly Hollow - T. L.  Haddix
"I have you now." "So you do. What are you going to do with me?" He lowered his head, rubbing her cheek with his, "I figured I'd love you."

Two things I really liked about this book were:
1)It was set in the 50s/60s (even though there were only a couple of references to this time period.)
2) It takes place in Appalachia.
It starts out kind of slow, but the reader needs those first few chapters to understand how long Owen has loved Sarah, even if he didn't know it himself. The relationship between the two is easy-going and playful. There is some tragedy, but they find their way back without much trouble.
