This 120 page volume includes five stories: the escape of Daniel Collins; Captain Franklin's 1845 Arctic expedition; Mary Reed, a female pirate; the Wild Men of Andamans; and Barbarossa. Each story starts with a map of where it took place, and ends with a historic overview of what else was going on in the world at the time. The end of the book has a nice glossary for a variety of words students might not know. The stated Guided Reading Level on this is V, which apparently correlates to a 5-6th grade level.
This would be a good book for a young reader who craves nonfiction but also wants a riveting story of adventure and survival.
