Set in between the first book, 'Dragons are a Girls' Best Friend' and the 2nd book I have yet to write. I do not own HTTYD Thyra is a girl who loves to study dragons. Especially Changewings. So when she finds and injured female Changewing, her life seems to get better, but quickly spirals out of control when a new menace arrives on her Island. Claiming to have a way to get rid of the dragons for good. So now Thyra needs to use all her strength and courage to fight this new threat. Otherwise everything she loves and cares for, will be gone.
