Dumped by her fiancé, opinion columnist Lyla Dune returns to small-town Echo Cove to heal, and to help her parents prep their house for sale. When she decides to open a time capsule she buried in high school, past memories lead her to a diary filled with memorable moments from the last summer she spent at home, right before college. Some of the events feel like they happened yesterday. That's normal. Not so normal is that they actually start happening all over again . . .

Lyla gets a flat tire in the same spot and is saved by the same person. The same movie is playing at the theater. Her house has the same leak it once had. As her current summer increasingly mirrors that last one, Lyla worries it will end just as disastrously: with a category 3 hurricane--and with losing Travis, the best friend she was always secretly in love with. If only she hadn't been too scared to admit it.

She revisits other fears too, like the fear of rejection that led her to abandon her passion for fiction writing. And when she reconnects with Travis, Lyla becomes certain that unless she does what her younger self was unable to do, she'll suffer the same regrets. But if this time around she can gather her courage, maybe the life that was falling apart when she arrived will fall back together--even better than before.
