[Full disclosure--I borrowed this book through Kindle Lending Club, so this is something I read for free.]
Lord of Pleasure (2009) is an entry from Delilah Marvelle's School of Gallantry series.
Lady Charlotte Chartwell, widowed when one of her husband's many mistresses killed him, needs money desperately. Her parents are dead, and her husband left her nothing in his estate. Despite being legally entitled to one-third of his estate, she isn't seeing much in the way of resolution by working through the system.
So what does she do? Proposition the first handsome man she finds, of course, while riding in a hired coach.
Alexander, aka the Earl of Hawksford, acts honorably when propositioned by a gentlewoman he doesn't believe is truly a widow. Despite a rather wild past, he (a) never paid for his pleasures and (b) wants to serve as a good role model for his young sisters since they became his responsibility on their father's death.
Imagine the surprise in store for both of them when Alexander's friend drags him off to join the School of Gallantry, a place created by a courtesan to teach men about what women really want, and where Charlotte is now the director of admissions. Alexander wants to become a student of the school, but only if he can have Charlotte as his own very personal instructor.
I enjoyed reading this historical romance, not least because Charlotte is practical, interesting, and more than a match for a reformed rake like Alexander, already in over his head with his mother and sisters. I can't imagine a character more in need of a good wife!
My overall personal rating of Lord of Pleasure is a B.
