Nevermoor : The Trials of Morrigan Crow Book 1 by Jessica Townsend

Enter the Wundrous world of Morrigan Crow and Nevermoor - the most fantastical children's series of the year. Morrigan Crow is cursed. Having been born on Eventide, the unluckiest day for any child to be born, she's blamed for all local misfortunes, from hailstorms to heart attacks - and, worst of all, the curse means that Morrigan is doomed to die at midnight on her eleventh birthday.
