What do you do when the boy next door turns out to be the only man you've ever loved?

When her sister is badly injured, Molly Schaeffer rushes home to look after her niece, Sara. Discovering that her ex, Jason, is living next door makes the task nearly impossible. Six years ago they'd been almost a family. He'd had their lives all mapped out - where they'd go to school, the house, the number of kids they'd have - but Molly refused his ring and broke off the relationship to pursue her own dreams.

The last thing Jason expects is to have feelings for the woman who broke his heart so completely when she chose her career over a life together, but clearly things weren't as over as they thought. She's only home for a few weeks and they both know she's going back to her successful career. Still, neither manage to keep their distance as old sparks ignite a new flame. Can they learn from past mistakes and give their love a second chance, or is this goodbye for good?
