Free-spirited travel influencer Hannah Spencer has spent five years touring the country in her vintage van, alone save for her hulking Great Dane, Dude. Until an unexpected inheritance from her pops has Hannah thinking about putting down roots in Cape Split, North Carolina, where she's the new owner of a worse-for-wear seaside beach house. Or, rather, fifty percent of one. Turns out Simon O'Malley inherited the other half from his gramps. As Simon and Hannah spend the summer tag-teaming repairs on the crumbling cottage, they discover it was once home to a timeless love story. As their own relationship shifts from enemies to friends to lovers, they begin to wonder if the house's romantic past might be a good omen for their future together. But there's one problem-Simon is set on selling the property at the end of the summer. For Hannah, the Split isn't like anyplace she's ever been, and Simon isn't like any man she's ever known-she doesn't want to let this new life go. She just needs Simon to see their budding relationship and this newfound community in the same way, or their first summer share might also be their last.
