Rocky to the rescue

When Rocky wakes up one morning, he discovers his house is deserted. With his mother, father and little sister nowhere to be found in-doors, he goes outside and discovers the animals are missing, too. When aliens arrive, Rocky realises that something has gone horribly wrong. Stowing away in the alien skimmer, Rocky sets out on his first and most important rescue mission, ever. Rocky to the Rescue is set on a station in the Australian outback, where help is often a long, long way away and the people must rely on themselves and each other. When Rocky's family disappears from their station in outback Australia, Rocky has to decide what to do next. Does he follow the aliens he thinks have taken them and try to get them back on his own, or does he travel hundreds of miles to get help from the neighbors and risk the aliens leaving before he gets back? Rocky to the Rescue is the first book in the Otherworld Adventures series
