28 Summers by Elin Hilderbrand

When Mallory Blessing meets her brother Cooper's college friend, Jake McCloud, she's a"complete goner." Mallory lives on Nantucket in an oceanfront cottage she inherited from her Aunt Greta. Jake is visiting with Cooper over Labor Day weekend in 1993, and when Mallory and Jake find themselves alone for the weekend, they become romantically involved. However, it turns out that Labor Day weekend is the only time they will spend together annually for almost thirty years, despite their deep bond. Jake lives in Washington D.C. and has had an on-again, off-again girlfriend--driven lawyer Ursula de Gournsey--while Mallory loves island life and can't imagine ever leaving Nantucket. 28 Summers recounts Mallory's and Jake's lives over all those years. Author Hilderbrand is in fine form. A great beach read that I had a hard time putting down.
