The World's Worst Alien

"a wild and witty ride packed with great gags" - Waterstones

When alien “Sky” creates planet Earth as part of a school project, she’s delighted by her success. Those dinosaurs roaming about the place are top-mark material! Then humans sweep in and it’s farewell dinosaurs, hello destruction. This disappointing evolutionary twist calls for drastic measures: Sky, the laziest student in class, is going to have make an effort, go down to Earth and fix humanity…

Hilarious observational humour and witty social commentary combine in this debut comedy of an alien reluctantly coming to Earth to “fix” the mess that humans have made of her school project.

Brilliantly illustrated throughout by Fred Blunt.

 

Praise for The World's Worst Alien

Selected as one of Waterstones Best Children’s Books for June 2025

“A side-splitting comedy based on the genius conceit that a very lazy alien is responsible for the creation of Planet Earth, Primmer’s debut children’s novel is a wild and witty ride packed with great gags on every page.”

Waterstones

“A fresh, funny debut… An outsider’s view of human behaviour creates brilliant observational humour that young readers attending school will enjoy.”

The Bookseller

“This debut is a hoot – laugh-out-loud funny and with a strong social message, this is perfect for reluctant readers and fans of David Walliams et al.”

Parrot Street Book Club

“This book is absolutely hilarious and the characters sound so real. They almost talk exactly like my own UKS2 students.”

NetGalley Reviewer
