4.5 stars 
 I agree with everyone, this book's amazing. I can't think of anything original or new to write, so I suggest you to just read the other reviews. 
 Why, 4.5 if I loved this book that much? Because of the too much used of poker analogy that affected the story sometime. It's obviously that the writer make research, the problems it's that she used too much of her new knowledge (same problem than in Nowhere Ranch and the BDSM scene). 
 It's a story that I'm going to read again with the same pleasure.
