A typical December for the Alexanders consists of gingerbread baking, movies, and looking at Christmas lights, but after their parents are called in to work, Ava, Nolan, and Charlotte are sent to stay with their most feared relative for a week-Great-Aunt Poppy. Have mom and dad gone mad? Of course, the children are terrified. Who wouldn't be? No one believes them when they say that Poppy-or Groppy as they call her-is a witch. If the haunted house isn't bad enough, there are thousands of crazy cats, chaotic and deadly spells, and even worse-frightening howls from the woods that grow louder and closer every second. Something deadly lurks outside. Staying alive while living with Groppy for an entire week is-well-impossible! In order to survive the holiday, it will take all the bravery and wit the kids can muster. But who knows? Things aren't always what they seem! The best holiday surprise this Christmas might be hiding in the most unlikely place imagined!
