What’s it about?

The story.

Barry Loser gets exactly the birthday present he wanted: the amazekeel Shnozinator 9000 gaming helmet. Unfortunately, his baby brother breaks it, which is clearly a catastrophe of the highest possible order. Barry's solution is not to accept defeat, save up slowly or behave sensibly; instead, he decides he will become a billionaire inventor and make enough money to replace it. This eighth book gives the series a slightly more gadgety, invention-led flavour while staying firmly in comic school-and-family territory. The appeal is classic Barry: enormous emotional reactions to small domestic disasters, overconfident schemes, silly product names, doodly illustrations and a constant stream of jokes. It is a very strong reluctant-reader option because the premise is instantly understandable, the chapters move briskly and the illustrations keep rewarding the eye even when the prose gets longer.

How it works in school.

A riotously silly illustrated series in a one-of-a-kind voice — catnip for reluctant readers and a classroom-library favourite.

A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.

Why it lands

Why they love it.

Why kids love it

The specific kick is sudden money — Barry deciding he's going to become a billionaire inventor after his baby brother breaks his Shnozinator 9000. The Barry Loser where the wish-fulfilment premise is everyone's favourite: enough money to fix everything, plus the misuse of it.

  • Trickery and cleverness
  • Revenge on adults

Why parents love it

The Barry Loser for a child fantasising about being rich — invention premise, gadget chaos, the usual doodly-cartoon presentation. Late-series; works fine on its own. Reliable for the reluctant-reader 7-10 shelf.

  • Shared humour
  • Quick to read

About the author & illustrator

Jim Smith.

JS

Jim Smith

Writer & illustrator · United Kingdom · b. 1971

Jim Smith is a British author-illustrator born in 1971, best known for the Barry Loser series of doodled-diary chapter books and the Future Ratboy graphic-novel-comic-hybrid series. The Barry Loser books, narrated by world-class loser-in-his-own-mind Barry, with hand-lettered, wonky text and constant in-jokes, are a UK-flavoured cousin of Wimpy Kid and Tom Gates, with the same reluctant-reader pull. Smith's voice is gleeful, unpretentious and quietly observant about playground social rules. Strong appeal for ages 7–10, particularly for British children who recognise the school-lunch, breaktime, brother-pestering register. Not to be confused with Jeff Smith (Bone) or with comics writer Jim Smith.
