Query: a gratifying read

There is much to be said for this account of Aaron Smith's harrowing experience among pirates who terrorized the seas during the early nineteenth century. Captured and forced to work as their navigator, Aaron walks the reader through his daily activities and the many thoughts and feelings that he experienced during his ordeal. His observations, internal and external, are keen. His descriptions seem winningly quaint, the way only true historical writing can. He also provokes the willing reader to examine a very uncomfortable and 'timeless' truth: if a captive does not placate his criminal tormentors, he will be killed; if he placates them too much, he may be identified with them and tried as an accomplice when rescued (apprehended?) Mr Smith takes us to scary places in both his world and ours.
