Sally Tinker – the world’s foremost inventor under the age of twelve – has developed her greatest invention yet. But when Sally’s baby brother Joe swallows it with disastrous (and gaseous) consequences, Sally and her friend Charli must shrink themselves, venture into the very bowels of Joe, and shut down the invention before it’s too late. What could possibly go wrong?

‘Fun, funny and filled with farts, Gastronauts is a wild ride not to be missed.’
Kids’ Book Review

‘hilariously funny … it will  be devoured by emerging readers. Perfect for school and public libraries.’
-Magpies Magazine

For Dungzilla:
4.5 out of 5 stars. Told in a highly graphic style through illustrated panels, this is a genuinely funny story that’s also packed full of knowledge. Beginner readers aged six to eight will not only laugh themselves stupid at the plethora of poo jokes, they’ll also learn a lot about insects and biology.’
– Junior Books+Publishing

‘I liked the book because it was very action packed and so funny … it was different and like nothing I’ve ever read before … I really enjoyed reading this book and I think other children would enjoy this book too.’
– Aaliyah, age 9, YARR-A

” [The S.Tinker Inc.] books are absolutely hilarious! Some of the funniest books I’ve read.
Confident readers will love them but they are great to hook those kids who ‘don’t like reading’ …
an invaluable addition to your graphic novel collection.”
Zac McCallum, My Best Friends Are Books
