Exhausted veterinarian Morgan Pearce is feeling overworked and under-thanked, so when two favorite clients ask her to watch their special needs senior dog in their Nantucket home, she jumps at the chance for a summer break. She hopes her time on the island will be a reset from the stress of her everyday life, but her chill vacation vibe takes a hit when she gets roped into fostering a challenging, anxious dog and helping plan the local rescue group’s glittery annual fundraiser.
 
Her trip starts to feel more like a vacation when Morgan begins falling for Nathan Keating, an irresistible entrepreneur who thinks every problem can be solved on a surfboard. Just as the summer is shaping up to be the magical refresh she needs, thanks to a fling that feels like the beginning of something real and Hudson, the foster dog who reminds her how much she loves her job, a visit from her estranged brother and the discovery of who Nathan really is changes everything. Morgan finds herself at a crossroads, trying to determine if mistakes from the past must define the future, or if she should forgive, forget, and grab hold of a chance to finally rescue herself.
