Theophile Gautier 
Mademoiselle de Maupin Volume I & II 

A woman uses her incredible beauty to captivate both d’Albert, a young poet, and disguised as a man, his mistress, Rosette. In this shocking tale of sexual deception, Gautier draws readers into the bedrooms and boudoirs of a French chateau in a compelling exploration of desire and sexual intrigue, and gives voice to a longing which is larger in scope, namely, the wish for completeness in oneself.
