In the early stages of writing Hypatia Academy, I knew that Hope would become friends with twin boys, but I didn't have names for them right away. Then one day, my older daughter and I were swimming at our local pool. Behind me I heard a mom teaching her sons to swim, and calling them by name. Their names, of course, were Arthur and Walter. I didn't even see the real life Arthur and Walter, but when I heard their names, I thought they were perfect for the twins. The real Arthur and Walter aren't twins, and just like with the kids from my former school, I didn't know them well and any similarity in personalities is simply coincidence.
