Overall Fifty Shades Darker is an enjoyable story to read. It is a love story, with a little BDSM mixed in. Ana and Christian try to help each other overcome personal obstacles, bringing them closer together, and building a solid relationship.
This little book is great if you are just looking to spruce up the sex life. One of my favorite things to do is to close my eyes, flip to a random page and that's the position for the next session. It is worth the short investment.
A love story with a little kink, though I think it is poorly written, is still intoxicating to read. You get so wrapped up in the world of Christian Grey and Anastasia Steele you forget about the repeating lines. You are held on by the steamy sex scenes and the growing relationship.
Overall, this is a great erotic read. It may even encourage you to spice up your love life. However, if you already have particular fetishes, it may not be the book for you. I found the plot of the story, aside for all of the overt sexual overtones to actually be quite interesting. The book definitely pulls you and and leaves you wanting more.
