When Cassie is named executor of her late grandmother's estate, she has no choice but to return to the coastal hometown she fled at eighteen. She has no interest in facing all the demons that have haunted her for the last decade, but she can't refuse her beloved grandmother's last wish. She'll get in, get everything set, and return to her life.

What Cassie doesn't anticipate is encountering Eli, the childhood best friend she had to leave behind when she left town, right before they were able to become something more. He now has a young daughter, and, noticing him struggling as a single dad, Cassie offers to babysit for the summer. While their relationship is cold at first, they soon remember why they fell for each other in the first place.

With Eli and his daughter, Cassie finds a happiness she didn't believe was in the cards for her anymore. But when Cassie comes across the reasons that made her run in the first place, Cassie must decide whether avoiding her fears is worth risking the precious love she's found.
