Hi, I'm Mark Hendriksen, a children's book author based in London. Here's a recent clip of me being interviewed at The London Book Fair in March 2025. 

I've been a publisher for some time, for the tourism industry and the first in a a series of children's book I've written is out now. Meanwhile another 4 (WIP titles below*) are written and heading via the editors and illustrators towards publication from 2025.

'All Animals Poo and We Do Too', an A-Z journey through the world of poop. Published18th August 2023.

These fun and informative books are perfect for children and parents who want to explore and get to the bottom of the fascinating world of poop, including our own.  

With colourful illustrations by the award-winning Canadian illustrator Keenan Hopson, 'All Animals Poo and We Do Too' (the first in a series) takes readers on a hilarious and educational journey through the world of poop. From ants (in your pants) to zebras, this book explores the different types of poop produced by animals and humans, and provides fascinating facts and anecdotes along the way, mixed with a touch of humour.

You can order the first book from leading bookshops and on Amazon, or as an e.book, 'All Animals Poo & We Do Too', and/or read my upcoming blog post publications for some useful information and updates + general poop news.
