Blast off on the biggest micro-adventure yet with the popular Project X characters Max, Cat, Ant and Tiger and their new robot micro-friend, Eight. Carefully levelled and highly motivating, this book is ideal for independent reading. The Excelsa is running low on holotanium. Without it, the micro-friends might not make it back to Earth. They take a detour to Planet Ashriss to try and find some more. On landing, Tiger's watch malfunctions and he ends up growing to giant size! Max, Cat and Ant meet some insect-like Ashrians, who tell the children that their holotanium source has been blocked. Giant Tiger manages to fix the problem ...but is then captured by Badlaw and his Krools. Together, the Ashrians and the children have to face Badlaw and carry out a daring rescue attempt. This book also contains notes on the inside front and back covers that highlight challenge words, prompt questions and give a follow-up activity to support children in their reading and comprehension skills.
