Nonfiction books

Huh. I just realized that I've read three four nonfiction books so far, and I'm in the midst of reading two more! Will wonders never cease? Will I actually read five six nonfiction books this year?

In an incorrect order...

The Pirate Queen: In Search of Grace O'Malley and Other Legendary Women of the Sea by Barbara Sjoholm
The Floating Brothel: The Extraordinary True Story of an Eighteenth-Century Ship and Its Cargo of Female Convicts by Sian Rees
