After reading FIFTY SHADES OF GREY, I looked for other books in the same theme. I admit that this trilogy is really great. I do not regret my purchase and highly recommend it. While the basis of the story is somewhat similar .... however we enter the direct subject of lively the 2nd chapter. No downtime. I devoured these 3 volumes. Much more detail than FIFTY SHADES OF GREY. In short a treat .... a must read ....
