Courting the Beast — R.J. Ross

Book 1 of the Winstead Files. In "Courting the Beast" a tomboy princess is turned into a beast and the best looking guy in town has to save her! If he can beat her in basketball, that is. With fairytale curses going out of control and a know-it-all fairy godfather not doing much to help, who knows where the happy ending will come from?
