Love is timeless So too is heartbreakWhenever a bird flies into a window in Spring Green Wisconsin sisters Milly and Twiss get a visit Twiss listens to the birds heartbeats assessing what she can fix and what she cant while Milly listens to the heartaches of the people whove brought them The two sisters have spent their lives nursing people and birds back to health But back in the summer of Milly was known as a great beauty with emerald eyes and Twiss was a brazen wild child who never wore a dress or did what she was told That was the summer their golf pro father got into an accident that cost him both his swing and his charm and their mother the daughter of a wealthy jeweler finally admitted their hardscrabble lives wouldnt change It was the summer their priest Father Rice announced that God didnt exist and ran off to Mexico and a boy named Asa finally caught Millys eye And most unforgettably it was the summer their cousin Bett came down from a town called Deadwater and changed the course of their lives forever.
