Some of my mom friends and I were discussing this -- many of our second graders have recently finished the Harry Potter series and LOVE it, both boys and girls. We are all scrounging around looking for other series to read, and HP is a tough act to follow. Then we were trying to come up with series that have girl protagonists. Other than Little House and Harriet the Spy, I haven't come up with a lot. Ideally we want books that are still gender-neutral in content (so, say, not fairies), and similar to HP in difficulty (so Clementine is too easy). Any ideas for us?
