Congruent Triangles

We review the seventh of this year’s nominees for the Book of the Year


X and Y are the anonymous authors of Congruent Triangles (Amazon UK), a book that tells the story of the daughter of a mathematician and a group of mathematicians/spies that come to stay at her ancestral home.


If you’re looking for a book that’s half Mills and Boon, a third spy novel, and a sixth maths textbook, then Congruent Triangles is exactly what you want. The book doesn’t take itself too seriously: in the authors’ own words, this book is “pure trash”. Despite its knowing trashiness, this book is well-written and entertaining.


There are some really nice bits of maths in this book, that are seamlessly intertwined with the story.


There aren’t very many mathematical fiction books, and there are even fewer of these that are aimed at adults with a reasonably high level of mathematical knowledge. This book is almost unique in filling this niche.


If you’re looking for a mathematical spy-romance novel, then this is the perfect book for you. If this doesn’t sound like your cup of tea, I recommend trying it anyway: you might be surprised how much you enjoy it.


You can vote for your favourite book on the Book of the Year shortlist below. The winning book will be crowned the Chalkdust Readers’ Choice. Voting closes at 1pm (BST) on Saturday 31 March.
