The Whitby Witches (Whitby, Book 1)

At first glance, the small seaside town of Whitby seems quiet and charming, but eight year-old Ben and his older sister Jennet soon learn that things are not always as they seem. Moved about from foster home to foster home, Ben and Jennet hope to make a fresh start in Whitby. But Ben sees things and people others cannot. There's something unusual about Alice Boston, their new guardian. And what is that horrible howling Jennet hears late at night? Something wicked's brewing in Whitby. Can Ben and Jennet put it to rest?
