Joshua started this book at the age of 12 as a home-study project. The original idea was a collection of puzzles to share with his local Potential Plus UK Explorer group – Surrey Explorers. It developed into this very interesting puzzle collection of 80 pages!

The book reflects a combination of interests and studies over a two-year period. It is very loosely based on Key Stage 3 topics. The authors are very grateful to famous authors for showing some of their own-published puzzle works to inspire them.
