My Hamster Is an AstronautPaperback, 1 March 2013

Nine-year-old Benjamin Jinks and his grumpy hamster, Jasper Stinkybottom are back - and this time they are shooting for the moon! Benjamin is a very normal boy who hates maths, but dreams of sending his hamster into space. Stinky is a hamster-genius, who has grudgingly accepted Ben's challenge - but can the pair win the science fair prize ahead of their scheming neighbours? Or will their experiment bring them back down to Earth with a thump?
