The first in a high-energy, hilarious and highly-illustrated young-fiction series from award-winning author – and everyday postman – Ben Davis. Postman Planet has a big secret. ​LOOK AWAY NOW IF YOU CAN’T KEEP SECRETS. ​ Although he PRETENDS to be the best postman in the Universe, he’s actually only nine.  Anyway, he's on a mission to make an essential delivery to the Planet of Fluffy Unicorns: an inflatable planet that is, as we speak, deflating. It’s up to Postman Planet and his ANNOYING new assistant Stamp, who is part-robot part-dog, to save the day.  ​ ​
