The Regenta, by Clarín
In 1884, Leopold Alas, better known by his pen name of Clarín, wrote a massive novel which would eventually be regarded as one of the 19th century's best. La Regenta is a fictional account of the life and loves of Ana Ozores, a noblewoman who marries a man far older than herself, but allows herself to be pursued by two other suitors: the town's resident heartthrob and a priest. Scandal!
