Crowne of the Withered - Alexa Bessee - Bog

Scarlett has only known Scout for a short time, but with nothing to do except wait out the snowstorm, she doesn't mind his company. However, the day takes an interesting turn when Scarlett finds the key that unlocks her cellar door, and the two find themselves emerging into a different realm where kings and queens still reign, magic is a part of everyday life, and people can shift in and out of dragon form at will. Months later, just as Scarlett is getting used to her new life, she is kidnapped from a battle and taken to an unknown island. Now, with no idea where she is and with no allies, all she has is the hope that her family is looking for her.
