A fascinating and fantastically funny guide to inventions that changed the world (and some that definitely didn't)

Kay’s Incredible Inventions

Winner of the Laugh Out Loud Book Awards 2025 (non-fiction) 
 
Do you ever wonder where the stuff around you all came from? No, not from eBay. I mean, who had the amazing idea of making a mobile phone or the annoying idea of building a school? For example, did you know that Velcro was invented by a dog and WiFi by a movie star? (Spoiler alert - it wasn’t Zendaya.) 
 
In the fourth laugh-out-loud book from Adam Kay and Henry Paker, you’ll learn all about the coolest, grossest and most ridiculous inventions in the world. You’ll meet the queen who used the first ever toilet, learn why margarine used to be full of maggots and find out why Ancient Greeks wiped their bums on dinner plates. Oh, and hopefully some slightly more useful facts as well… 
 
An A to Kay to Z of the random, ridiculous and revolutionary inventions that changed our lives. (And some that definitely didn't . . .)

The laugh-out-loud picture book from bestselling Adam Kay and Henry Paker

Amy Gets Eaten

The first-ever picture book from Adam Kay and Henry Paker - now Children’s Picture Book of The Year 2024 – The Week Junior Book Awards! 
 
The judges said: “This poo-filled picture book [...] reveals scientific facts in an engaging, silly and original way, with lots of icky illustrations to add to the fun.” 
 
This is the hilarious (and admittedly a tiny bit gross) tale of Amy, a small piece of sweetcorn who is eaten by Noah, a medium-sized boy. The story follows Amy on her funny, gooey and anatomically-accurate adventure through the human body as she discovers lots of facts about digestion. (It's fair to say that parents might learn a little bit too.)

A Gross and Gruesome History of the Human Body

Kay's Marvellous Medicine

The hilarious history book for kids, all about the human body, from bestselling, record-breaking author and illustrator Adam Kay and Henry Paker. 
 The olden days were pretty fun if you liked wearing chainmail or chopping people's heads off. 
But there was one TINY LITTLE problem back then . . . doctors didn't have the slightest clue about how our bodies worked. 
 It's time to delve into history and get some answers to some big questions, like: <ul><li>Why did patients gargle with wee?</li><li>Why did people used to get paid for farting? (Unfortunately that’s no longer a thing – sorry.)</li><li>How did a doctor save people's lives using a washing machine, a can of beans and some old sausages?</li><li>What was the great stink? (No, it's not what doctors call your bum.)</li></ul> 
 If you're sure you're ready, then pop a peg on your nose (there was a lot of stinky pus back then), pull on your wellies (there was a lot of poo there too), wash your hands (because they certainly didn't) and explore this gross and gruesome history of the human body!

 It's time to find out why Ancient Egyptians thought the brain was just a useless load of old stuffing that might as well be 
 chucked in the bin, why teachers forced their pupils to smoke cigarettes, why hairdressers would cut off their customers' 
 legs, and why people used to get paid for farting. (Unfortunately that's no longer a thing - sorry.)

A Complete (and Completely Disgusting) Guide to the Human Body

Kay's Anatomy

THE RECORD-BREAKING NUMBER ONE BESTSELLER FROM THE UK'S BESTSELLING NON-FICTION AUTHOR. 
 
Discover all the weird and wonderful things that go on inside your body with Adam Kay. This fun-filled anatomy book for kids covers key stage 2 / 3 human biology syllabus (in a slightly repulsive way). 
 
'Hilarious and fascinating! I wish Adam had been my biology teacher' - Konnie Huq 
 
Do you ever think about your body and how it all works? 
Like really properly think about it? 
 
 
The human body is extraordinary and fascinating and, well . . . pretty weird. Yours is weird, mine is weird, your maths teacher's is even weirder. 
 
This book is going to tell you what's actually going on in there, and answer the really important questions, like: 
 
Are bogeys safe to eat? 
Look, if your nose is going to all that effort of creating a snack, the least we can do is check out its nutritional value. (Yes, they're safe. Chew away!) 
 
And how much of your life will you spend on the toilet? 
 
About a year - so bring a good book. (I recommend this one.) 
 
So sit back, relax, put on some rubber gloves, and let a doctor take you on a poo (and puke) filled tour of your insides. Welcome to Kay's Anatomy*. 
 
*a fancy word for your body. See, you're learning already.

Dexter Procter and the Case of the Disappearing Doctor

All is not well in the world with Dexter Procter, the world's youngest doctor. 
 
His granny has broken her leg, his friends Rupi and Otto have been expelled, there's an asthma epidemic he can't get on top of, and everything fun at the hospital has been shut down by slimy politician Barbara Burnhall. And then his boss Dr Marigold disappears off the face of the earth! But what Dexter doesn't realize is that he and his friends are about to uncover a dastardly plot featuring kidnap, earthquakes and a runaway ambulance. Dexter Procter doesn't know what's about to hit him. (Spoiler alert: it's a runaway ambulance.) 
 
Adam Kay and Henry Paker have created a second Dexter mystery that is funnier, more ambitious and even more disgusting than the first book (and that was pretty disgusting). 
 
Dexter Procter and the Case of the Disappearing Doctor is soon to be a major BBC show.

Adam Kay

Henry Paker

The highly-acclaimed, No. 1-bestselling children's fiction debut from Adam Kay - and soon to be TV special from the BBC! 
 
It was clear from an early age that Dexter Procter was different. 
 
He started speaking at four seconds old. By the age of three, he had 87 A-levels, from Afrikaans to Zoology. 
 
And by ten, he was working as a paediatrician at Lilydale General Hospital. 
 
Despite a loving but annoying family and a couple of good friends (Rupi and Otto), Dexter’s always struggled to fit in. Add to this a mortal enemy (Dr Drake) and a major problem at his old school (all the teachers struck down with awful diarrhoea) – will Dexter be able to save his job, save the school and find his place in the world? (Spoiler alert: yes!) 
 
A laugh-out-loud new fiction series about the world's youngest doctor from the record-breaking Adam Kay and Henry Paker. 
 
'Original, very funny, ultra-informative - and children will love all the disgusting parts.’ Jacqueline Wilson 
 
'If laughter truly is the best medicine, book this hilarious appointment with Dr Procter immediately.' David Baddiel
