Rainbow Rowell: Hello. My name is Rainbow Rowell. An easy way to remember how to pronounce my name is that it rhymes with towel. My first name, Rainbow, is very unusual. Everyone in my family has unusual names. When I was younger, I hated my name. I always wanted to change it, and my mom said, "Okay, sure, you can change it when you're 18." I thought I would change it to Sarah with an H. But then by the time I was 18, I thought my friends would never take me seriously if I told them to start calling me Sarah.
