I had little to no expectation for this book (It's the first of the series I've read) and I honestly loved it. The relationship between the main characters was intresting and there were a lot of sex scenes whitout it being repetitive. The only thing I would say is that the inner monologues get repetitive at times, especially towards the last third of the book and that got me a bit bored. 
Other than that, if you like erotic BDSM books I would recomend checking this one out.
