The only bad thing about this book is that you’ll have to wait a few more months to read it: It doesn’t come out until March 2025. But I was lucky enough to get an advanced copy—and I’m so glad I did. Twelve-year-old Everly “Benny” Benedict finds she’s the heir to a mysterious fortune, but before she can collect it, she has to win a devious game.
Following clues an ancestor somehow knew to leave her, she must locate a mysterious island that hasn’t been seen in two hundred years. There’s great character, mystery, action—and pirates. Do yourself a favor and pre-order it!
