Olly Brown is Hamster obsessed.

But his dad won’t allow any pets, so Olly never gets to take the Year 6 class hamster home.  Then the most AMAZING thing happens:  a hamster shows up on Olly’s house!  It is really smart.  Olly soon learns it is one of many … and that there is a whole civilization of super-advanced, intelligent hamsters who seem to be worshipping Olly as a god?  How is this possible?
