In a fantastical world where boys spend their whole lives training to fight dragons, ten-year-old Rose wanted to be a boy. Girls were taught how to decorate castles, banners, buffets, and, lucky them, the boy's armor! Rose hated it. It was especially annoying that her six-year-old brother was already walking around with his chest puffed out, bossing her around, as if he'd slain ten dragons on Tuesday. But at least Rose could do one cool thing-she could make gemstones fly. The castle's treasure hoards were filled with fire diamonds, jungle rubies, ice emeralds, sugar sapphires, and she couldn't name them all, but she had to admit, the family's jewel collections were a beautiful thing. Don't tell her mother though, because apparently it's impossible for a girl to love pretty things and want a steel sword for her birthday.
