I received free copy of Madame X from NetGalley and the publisher in exchange for an honest review. Madame X is edgy, twisted, and dark story of a young woman whose job is to train and transform young privileged boys into sophisticated men. She works for Caleb who "rescued" her after she was brutally attacked six years ago. I found the idea behind the story is unique but I did not like the main characters at all. 
 First of we have Madame X who basically lives in her gilded cage, does what she is told by Caleb, who is her savior (or her captor depending on one's point of view) and never questions him or her limited freedom. She is not allowed to leave her apartment, meet people who are not her clients or make friends. She is passive, she does not make any decisions or acts on her own, she only reacts to other people's actions. I could not warm up to her, even though her back story is interesting. Madame X was attacked, almost died, and lost her memory completely following the attack. She doesn't even remember her name, has only memories of the last six years and knows only what Caleb tells her. Then we have Caleb who, in my opinion, has no redeeming qualities whatsoever and is just plain horrible character. Although he does not physically abuse Madame X, he is definitely manipulative and emotionally abusive. The only interesting character is Logan, mysterious man whom Madame X meets during one evening while she is attending an event and feels instant connection to him. This meeting prompts Madame X to finally question her twisted relationship with Caleb. I definitely wanted to know more about Logan. 
 The mystery of who Madame X is and what happened to her in the past was the most interesting part of the story. Unfortunately the author does not offer any clues to reader in this book in order to begin unraveling the mystery and therefore even this part was a little unsatisfying. 
 I love tough alpha heroes and I love sensual, erotic and even kinky stories as long as everything between H and h is consensual. Dark romance in which emotional or physical abuse presented as some sort of misunderstood love story is not my cup of tea. I should have stopped reading this book when I realized this was dark romance. Although I didn't actually hate this book I didn't like it either
