This title is part of Bug Club, the first whole-school reading programme to combine books with an online reading world to teach today's children to read. In this Year 6 Red B (NC level 5b) non-fiction book… Imagine a world without maps. A time when few people knew what was outside their village let alone over the horizon. Then up popped some great adventurers who boldly sailed out into the unknown. But what made them risk life and limb to do it and how did they change our view of the world? This book is part of the 'Dead' mini-series of books, Dead Gorgeous, Dead Losses, Dead Sick and Dead Adventurous - looking at some of history's greatest characters and events.
