The Kerfuffles is an illustrated series of fictional children’s novels following a day in the life of the Kerfuffle family living in Australia. The series commences with the family moving into a decrepit old house in the suburbs. Not only do twins, Drake and Cindy Kerfuffle, have to deal with the unbearable Summer heat and pesky mosquitoes, but also their annoying parents and elderly relatives. Funnily enough, Aunty May and Uncle Harold surprise the family with an unexpected visit over the Summer Holidays and, strangely, refuse to leave.
