What to read after Henry and the Clubhouse?

For Henry Huggins and his friends Robert and Murph, a clubhouse is a place where they can do as they please, without being bothered by girls. The sign that says No Girls Allowed -- This Means You especially means Ramona Quimby. Lately Ramona has been following Henry on his newspaper route, embarrassing him in front of Henry's customers. The day Ramona follows Henry to the clubhouse, she wants to teach him girls aren't so bad, but she almost puts an end to his newspaper career forever.
