Become a number ninja with this action-packed pick-your-path adventure story!

Two legendary ninja clans - the unpredictable Odd Squad and the disciplined Even Order - are locked in a centuries-old rivalry. The sudden theft of The Infinity Code, an ancient encrypted sequence rumoured to unlock limitless power, has brought the conflict to the brink of an epic battle.

The Infinity Code isn't just read - it's a puzzle to solve, broken into pieces, hidden in logic traps, games and enemy strongholds. Each piece you solve grants a surge of skill or strength. Complete the Infinity Code, and your abilities will be amplified to the power of infinity.

This fun, maths-themed puzzle book challenges you to choose your clan, master its style, outwit your rivals and decide who should hold such unstoppable power. Complete ninja training rituals to sharpen your number skills, intercept rivals in logic duels to capture code segments, choose your own adventure and unlock the true ending. Only by mastering both clans' methods can you solve the final sequence!

The pick-your-path format with branching storylines, along with its hidden symbols and secret codes, means you get a different story every time you re-start the book. Each puzzle you complete impacts on the plot, so you can read and play over and over again.

Perfect for readers in Key Stage 2, Clash of the Ninjas makes maths challenges fun and accessible and will aid with numeracy and arithmetic as part of an immersive, interactive and exciting story.
