Life, Adventures & Piracies of Captain Singleton, The by Daniel Defoe (c.1660 - 1731)

The Life, Adventures & Piracies of the Famous Captain Singleton is a "bipartite adventure story whose first half covers a traversal of Africa, and whose second half taps into the contemporary fascination with piracy. It has been commended for its depiction of the homosexual relationship between the eponymous hero and his religious mentor, the Quaker, William Walters." (Summary by Wikipedia)
