I enjoyed this 4 book series very much. I fell in love with Flynn and Natalie, and their powerful love story, and met all the Quantum players in the first 3 books. What I really like is that each woman is strong, powerful, and resilient without the man, and with the man they become brighter, and make their men do better. I love how the characters are all friends and family and how they all respect each other. These books also explained the lifestyle of dominants with a submissive carefully with emotional detail. The sex scenes are extremely well done, and very steamy!I am so glad that Addie got her Spencer. She totally deserved to get her man, and he totally deserved to be happy! Really glad Amazon and Goodreads suggested Marie Force to me.
