paperback - good condition Henry and his friends are building a no-girls-allowed clubhouse. With a private space of their own away from everyone else—and even a top secret entry password—they're all thrilled with their boy fort. But Henry's about to find out that nothing—not even a sign—will keep gutsy Ramona out of their clubhouse…and her retaliation may just ruin Henry's newspaper career.
