I would classify this book as a love story set in a fantasy world rather than erotica or BDSM even though it is about a whorehouse of boys for men and whips play an important role. All of the sex and s/m elements take place behind closed doors.The relationship between the two men who own the whorehouse, Michael and Janus is one of those unforgettable pairings that will live with the reader long after they finish the story.Catana's review sums up the plot really well.The world building is well structured and by basing her social attitudes on Edwardian times, the background morality holds an integrity that comes from fact.The research for Dusk's writing is always meticulous and well documented, but it never gets in the way of the story.At the end, you're left wanting more, as although there has been one emotional arc completed, none of the participants in this highly unusual triangle have what they really want. Yet, even if the status quo prevails, they will all have a certain degree of happiness.Highly recommended for those who want to read about love between men, but don't bother if you're just looking for romance (in the Harlequin form of the word) and/or sex.
