Parce que je t'aime

After chapter 6, I was really into knowing what was happening, what great mystery laid ahead, but the end was pretty disappointing.
I almost DNF at 96%, 
it was somehow disgusting, non creative to the point of reminding me of the last book of Twilight when Jacob imprinted Esmee. 
On a side note, I wonder what is the point in describing the skin color of characters when the white characters are never described or when the description adds nothing to the story beyond stirring the readers prejudices?
