Mathatar - Book One

Current status - in submission stage

When fourteen-year-old Maya discovers that reality is beginning to distort through mathematical slips, she is drawn into a portal hidden in her grandfather’s workshop and thrown into ancient Ur.

There, alongside Aya, Fletcher, Grandad and Fella the Labrador, Maya must confront the Null — faceless forces that are stealing mathematics from history.

If numbers, patterns, proof and structure disappear, reality itself may not survive.

The wider Mathatar world and series

Mathatar is planned as a series exploring the moments where mathematical understanding changed human history. There are plans for other subjects in the future to be covered.

Each book will combine adventure, emotional stakes, historical settings and a core mathematical idea — not as a lesson, but as part of the story’s engine.

The long-term vision is a series that helps readers feel that maths belongs to them: not as a test, but as a human story full of mystery, courage and discovery.

Mathatar will be offering educational support materials and events to complement the series.

Other writing

Alongside Mathatar, Adam has written two previous books, and writes articles and reflections on storytelling, education, confidence, creativity, communication, resilience and the way powerful ideas shape how we see the world.

His previous books include Cellular Attitude (2nd Edition), a personal guide to creating a happier life by understanding and processing traumatic events in your life and The Anti-Sales Manifesto, a psychology based approach to ethical sales that focusses on helping customers buy what they want.
