This is an exciting new series for boys who are reluctant readers. It is full of information on submarines from how they work, the different types (from exploration to military subs) to true stories of subs during the World Wars. Visually exciting and highly informative, each book presents its subject in a fun and accessible way with photographs, illustrated diagrams and comic strips. It includes three gatefold flaps showing the inner workings of a submarine and the large variety of submarines that exist today. Internet links offer a fascinating selection of recommended websites - with sound, animation, video clips and much more, which provide additional information for projects and homework.
