This hugely successful series is now available in a new smaller flexi format. The tried and tested formula of 100 sequential facts motivates children to read these books from start to finish. From cover to cover, beautifully detailed artwork will mean that even the most reluctant of readers will be totally absorbed by the fun activities, such as projects and quizzes. Humorous cartoons add a lighter touch, while the wealth of perfectly pitched information provides ideal introductions to the subjects.
