The first title in a new quartet from Sam Usher featuring the much-loved Boy and Grandad. This time they use their resourcefulness to mend, recycle and re-use to create a variety of favourite vehicles which take them on exciting adventures around the world - and beyond! ZOOM! sees them blasting off into space in their homemade rocket to mend a broken module and rescue two stranded astronauts.

A delightful family read, exploring creativity, celebrating recycling and deftly introducing subtle science and engineering facts - all the while following the enduring and heart-warming Boy-Grandad relationship.
