User blog:Sparrowsong/Story idea that I'm worried might be controversial

Ok, I have a story idea. I've already got a title picked out. The story would be called Dying Flowers, and the main character would be Flora King.

Flora is an unclaimed demigod. She is of mixed race (half African-American and half Caucasian). All her life, she's struggled with teasing, bullying, racism, and insensitive comments like "Are you black or white?" Then she goes to Camp Half-Blood, makes some new friends, and eventually realizes that it's not the color of your skin that matters - it's the color of your heart.

That last line sounds soo corny, LOL.

The thing is, I'm worried some people might be offended by it and call me racist. Do you think it sounds racist or offensive?
