Aptly named, the Dangerous Jobs series (6 titles) presents the history, challenges, and reality of more difficult career paths. Here readers dive into the world of underwater construction, where they’ll get a glimpse of this occupation’s daily work (tightening bolts, using power tools) and inherent dangers, which must all be navigated while wearing goggles and an oxygen tank. The volume works well at helping readers anticipate new sections, providing a thoughtful introduction to chapter books. Surprising facts about the long-standing history of underwater construction (since at least the 1500s!) pair with simplified diagrams of gear and interspersed vocabulary definitions. A concluding profile on Singapore’s first woman professional diver, who now does underwater construction, rounds out this high/low introduction to an unusual job that is sure to intrigue many.
