Do you like adventures? If so, you’re just like Theo, Seb, and Reja! Join them on an amazing journey to help a timetravelling dog (or whatever he is!) return to his home planet.

You’ll get the chance to outwit fearsome pirates, rescue a cat from prehistoric dinosaurs, and help build The Great Pyramid of Giza by solving tricky puzzles along the way.

In this book, you’ll become an active part of the story! Can you use your maths and problem-solving skills to help the adventurers on their quest? Can you use logical thinking to recover missing pieces of the rocket to help fire Kubit home? Why not find out?
