Every August, Elizabeth Ackerley returns to Nantucket. To the same beach house. The same ocean. The same sunsets. And Theo. But this summer is different. For the first time, Elizabeth arrives alone. Her family is falling apart, and the beach house that once echoed with laughter now feels painfully quiet. Still, August has always been her escape. And in just a few hours, she'll see Theo again-the boy she's spent every summer growing up beside, the boy she's never stopped missing. Some summers change you. Others change everything.
