Three children (Brendan, Elanor, and Cordelia Walker) and their parents move into a new house that was cheap but really nice. Soon after moving in, a witch takes the children and the whole house away, leaving the parents behind.
The children encounter several difficult situations that they have to work their way out of. This book is full of adventures with many unexpected twists and turns that I never imagined would happen. I found this to be very fun.
