The Sewer Rats

Riding the skycart into space for free earned the two young brothers the nickname of ‘The Sewer Rats’. When they visit a world so old-fashioned that they still use wheels and wrist-computers they are joined by two young sisters escaping from a game of hide-and-seek gone wrong.
They begin an adventure star-hopping between worlds, battling against deadly reptiles and strange telepathic ant-like creatures. They visit a planet where laziness is the norm, but so is dictatorship and police corruption. Aided by their intelligent bio-computer tattoo Newton, the four children battle against a mad general and a champion fighting tattoo intent on revenge.
Will they escape the rat-traps? And will they learn the plans the insects have for humanity?
