So I loved this book:
An earlier version of this post said that this was a companion book to MLND. I was wrong -- though the new book is set in the same general locale, it is a standalone! But I'm hoping it's the kind of Sarah Dessen or Stephanie Perkins standalone where the characters from MLND might make a brief appearance….
17-year-old Gwen Castle's Biggest Mistake Ever, Cassidy Somers, is slumming it as a yard boy on her Nantucket-esque island this summer. He's a rich kid from across the bridge in Stony Bay, and she hails from a family of fishermen and housecleaners who keep the island's summer people happy. Gwen worries a life of cleaning houses will be her fate too, but just when it looks like she'll never escape her past—or the island—Gwen's dad gives her a tip: her wealthy, elderly employer is redoing her will this summer, and that could be Gwen's ticket to the good life. But what will it mean for Gwen’s now life?
Sparks fly and secret histories unspool as Gwen spends a gorgeous, restless summer struggling to resolve what she thought was true—about the place she lives, the people she loves, and even herself—with what really is.
