The Wendelin family lives in a very peculiar house that suddenly jumps off to other places! The family find themselves in the middle of a parched savannah with a giraffe peering in through a window. Or in the middle of a pirate story where they try hard to avoid walking the plank before the next jump. With all this going on, it’s no wonder that the Wendelins are, ahem, unconventional. They often seem to annoy their respectable, straight-laced neighbours. But they have a faithful ally in their neighbour Lonni, a little girl who does everything she can to protect their secret. It would also help to find the family’s missing grandparents – they’re the only ones who know how to control the house and its jumps!
