2.5 stars? Wildly uneven & contains much creepy glamorization of piracy, including kidnapping, rape, murder, torture, drug trafficking, and slavery, with a laughably unconvincing statement of authorial moral disapproval tacked onto the end of a book otherwise full of describing perpetrators as "great" and "heroic". (Tbf, the 3 scariest get called "psychopath" too.)
Uh. *facepalm*
Also in facepalm territory, Konstam squarely blames lack of local law enforcement for the existence of piracy, and never once addresses the socioecononics of the place and time as a fundamental cause.
The historical detail wrt English-speaking pirates is pretty fantastic. Less so with other European languages, while the chapter on China is ridiculously thin and veers well into White Man's Burden territory by the end. Gah.
Better is the section on sanitized "piracy-lite" in pop culture, designed to appeal to get-away-with-it culture and little kids with anti-authoritarian streaks who nevertheless latch onto a firm code of pirate ethics, although it's pretty clear that the author has a giant crush on Johnny Depp.
