Iris Standish has always been the responsible older sibling: the one with the steady marriage, loving family, and sensible job. But all of a sudden, as her carefully-constructed life spins out of her control, a cryptic postcard from her estranged sister Leah arrives at the perfect time: Please Come. Iris seizes her chance to escape to her childhood lakeside home, where Leah is planning her summer wedding to a man their New Hampshire clan has never met. Against a backdrop of dress fittings, floral arrangements, and rehearsal dinners, Leah hides secrets of her own. And while her sister faces a past that has finally caught up to her, Iris prepares to say good-bye to a future that is suddenly far from certain. As new love beckons and Hampstead Lake shimmers in the background, Iris must decide when to wade in cautiously and when to dive, and ultimately, how to ferry herself to safe harbors in this enticing novel of second chances and the ties that bind.
