About This Book
Things are not going well for Jackson 'Jax' Hibert. He wanted to fit in at his new school but now everyone knows he's a maths whizz. Even worse, he's been asked to join a secret (and totally uncool) group of code breakers: the Codebusters. Their mission is to solve mysteries and fight crime. So far, they've found a missing hamster... But now, someone has stolen the school's math prize from the trophy cabinet, and the only clue is a mysterious code. This looks like a case for the Codebusters! Funny, exciting or a little bit spooky, Black Cats are fast-paced stories with short chapters and illustrations throughout - stepping stones to reading confidence. Book band: Dark Blue Ideal for ages: 9+
