So many of you have been asking us for the next books in the bestselling series and now we're delighted to say The Project X team are back - and they're set to face their biggest challenges yet in this massive 25-book collection.

Max, Cat, Ant, Tiger and their new robot micro-friend, Eight, face a number of new challenges that will inspire young readers to keep turning the pages of every single action-packed book included in the collection.

With stories written by authors including Steve Cole, Elen Caldecott and Jacqueline Rayner, the plots follow the gang as they face off against Badlaw; go in search of a missing cargo of cyberbees; and are attacked by a swarm of metal-eating, robotic space locusts. The collection also includes a larger-format Fact File full of activities.

With their 3D-style artwork, the books are perfect for children in Year 3 at school. All-new stories, they continue the adventures from the first series at Oxford Reading Level 9 and progress all the way up to Level 14, meaning they are suitable for children of differing reading abilities.

This 25-book collection covers Oxford Reading Tree Levels 9 to 14 (book bands Brown and Grey). It is suitable for children in Year 3 and 4. It follows on from the first collection back at Level 9 to help children hone their reading skills before moving onto the more advanced stories.
