Lark Farragut has just turned 10 and is about to embark on a glorious summer of sleep-overs, rambles by the creek, bicycle rides, sleeping in late, and catching up on TV. Better yet, her mom's gotten the entire summer off from work, so Lark won't have to put up with babysitters or day camp. Nope, it's just the dog days of summer for her, and she's going to share those lazy, fun-filled hours with her two best friends, Jennifer and Argy. The Three Divas, they like to call themselves.They've got girl power and they're ready to take on the world. And as far as Lark's concerned, enemy number one is Skip, a stupid boy who won't stop hanging around. He actually thinks his skateboard is a motorcycle. Boys! Lark thinks they're all pretty dumb.But as the summer unfolds, boys start to play more and more of a role in Lark's life. First, her more is dating again. It's been a few years since her dad left, but the divorce has finally come through, and now some creepy man named Milton is wheedling his way into their lives. Then there's Jennifer and Argy. They keep giggling over boys and they can't stop talking about them. And when Lark finds herself oddly drawn to the hated Skip, she decides it's time to take action. She comes up with her most brilliant plan ever -- creating a no-boys club to mount an all-out war against them -- but it backfires and the Divas' sisterhood begins to crumble. As the long summer wears on, Lark learns that not all change is for the worst.
