Mistress of the Storm — M.L. Welsh

Verity Gallant is a lonely little girl who doesn't quite fit in. But when a mysterious stranger hands her an ancient book, everything changes. Suddenly it's up to her to solve the riddle of an ancient pledge and protect her family from the evil Mistress of the Storm. What hope does she have against a witch so powerful she can control the wind and create storms at will? Luckily, Verity does not have to face her enemy alone. As events begin to spiral out of control, she finds two loyal and steadfast friends to stand by her side.

The Storm is coming. And it will change Verity's life forever.
