Fifty shades darker (fifty shades, #2) (as cinquenta sombras mais negras [Portuguese version])

By E. L. James:

It is the second volume of «Fifty shades of Grey (Fifty shades, #1)». Like the first volume, it is a book written primarily for women and it follows the same clear and coherent writing style. It remain eroticism and sickening sex scenes. The story seems monotonous until half of the book, but then turns out to have some interesting plot, which makes it better than the previous book. But again I emphasize that there are Harlequin books much better, interesting, and faster to read.
