Why do ships sink? What happens to them when they do? And how are their wrecks located?Join (the fictional) Dr Profundo and chart a course across the world’s oceans, seas and lakes, revealing the mystery surrounding more than 50 of the three million wrecks that lie under Earth’s waters. A comprehensive and engaging insight into the underwater world of shipwrecks, told in compelling narrative non-fiction style by a well trusted voice in children's books.Each spread has full bleed illustration and is annotated by the fictional explorer in charming narrative non-fiction style.Some spreads are dedicated to single wrecks and others taking in two/three/four (or more, for examples like the fleet of Kubla Khan, The Spanish Armada, Chuuk lagoon and the Tangalooma wrecks, where many wrecks are concentrated in a small area).See examples of ships in their heyday as well as in their underwater resting place, close-up detail of specific artefacts or points of interest, and information split into digestible chunks, rather than heavy slabs of text, with a combination of prose, ‘In numbers’ lists and ‘Did you know?’ bubbles. This is a perfect book for lovers of mystery and history and is a perfect Halloween-adjacent non-fiction armchair travel for children who love adventure.
