Two best friends torn apart by a life-altering secret. They have one summer to set the record straight.
When twelve-year-olds Kat Steiner and Blake O'Neill meet at Camp Chickawah, they have an instant connection. But everything falls apart when they learn they're not just best friends—they're also half-sisters. Confused and betrayed, their friendship instantly crumbles.
Fifteen years later when their father dies suddenly, Kat and Blake discover he's left them a joint inheritance: the family beach house in Destin, Florida. The two sisters are instantly at odds. Blake, who has recently been demoted from regular nanny to dog nanny, wants to sell the house, while social media influencer Kat is desperate to keep the place where she had so many happy childhood memories.
Kat and Blake reluctantly join forces to renovate the dilapidated house with the understanding that Kat will try to buy Blake out at the end of the summer. The women clash as Blake's renovation plans conflict with Kat's creative vision, and each sister finds herself drawn into a summer romance. As the weeks pass, the two women realize the most difficult project they face this summer will be coming to grips with their shared past, and learning how to become sisters.
