Dream-Maker's Magic — Sharon Shinn

Kellen's mother has always insisted that her only child was born male, not female -- so Kellen has been raised as a boy. At school, she meets Gryffin, whose mind is as strong as his legs are damaged, and the two become friends and allies. A few years later, the two get jobs working at an inn nearby. When it is discovered that Gryffin is the kingdom's new Dream-Maker -- someone whose mere presence can help dreams come true -- he is whisked away to the castle, leaving Kellen behind. By now, their friendship is shading into something more. Will it endure?
