I first wrote Piers Anthony back in 1994, when I was 14; I asked him to name a character for my pen pal's son, who had been a fan and had been murdered. He did.
I wrote him again in 2004; I asked him to Jane characters after my daughters because they have autism; again, he did. They are minor characters in the Xanth novel Stork Naked. I've provided an Amazon link to the book above for anyone who is interested in checking it out. It's through my affiliate link, so if you make purchases through that link I will receive a small commission. Any help is appreciated. (Autism is expensive!)
