Explorers are designed to appeal to all readers aged 6–8: those who are just starting to read alone and more confident readers who are beginning to exercise wider reading and crossreferencing skills. Lively, dramatic artwork scenes draw children into a subject, and each scene is followed by a photographic information spread that gives a wealth of extra detail. As a fun extra element, the reader can follow themed links to access information on related topics.

Explorers: Big Cats by Claire Llewellyn, illustrated by Peter Bull

It's impossible not to admire the beauty and strength of the world's biggest cats. In this book, children will learn about species such as jaguars, snow leopards, lions, and cheetahs. On one illustrated spread, they can see one moment in an actual cat's life―like such as the second before a jaguar charges into the water in southern Brazil, or a group of young cheetah brothers defending their home in The Kalahari Desert. Real-life photographs highlight more general information about these fantastic felines, such as a cat's anatomy, and the social life of a pride.
