Amber Scott, Meghan McCloud, and Brook Jones were born within weeks of each other. They've never met but are connected in a way that will change their lives forever.
After turning thirty, they receive a letter requesting their presence for the reading of James Cavanaugh's will, even though he hasn't died yet. They discover that they are half-sisters, and he's their father.
James always felt guilty and never forgot about any of them. After becoming a successful businessman and settling into a gorgeous house on Skaneateles Lake, he discovers he's dying. He hires a private investigator to look them up, wanting to make amends.
James plans to leave everything he has to his daughters. The only stipulation is they must spend the summer together with him at his lake house. If at the end of the summer they wish to go their separate ways, they will be free to do so. But will any of them be able to leave after discovering a place to call home?
