Dragon's Keep — Janet Lee Carey

Far away on Wilde Island, Princess Rosalind is born with a dragon claw where her ring finger should be. To hide the secret, the Queen forces her to wear gloves at all times until a cure can be found, so Rosalind can fulfill the prophecy to restore the family to their rightful throne.
But Rosalind's flaw cannot be separated from her fate. When she is carried off by the dragon, everything she thought she knew falls apart. The dragon sees beauty in her talon where her mother saw only shame, and Rosalind finally understands what her mother has truly denied her.
Carey has written a stunning portrayal of the complex relationship between a mother and daughter in a lyrical novel sure to thrill readers who love fantasy--and those who don't.
