I really enjoyed A Discovery of Witches. It does have a few Twilight like similarities but that didn't take away from my enjoyment. I was very invested in the story and what is going on with Diana and Matthew but I do have two complaints: 
 1. The use of "looks of ice and snow" and the like. All these cold looks drove me nuts. 
 2. The details. I never thought I would ever say this but there were too many details sometimes. Not with everything but there were a few times that I just wanted to get on with the story. 
 The audiobook is very long (24 hours-ish) but I really enjoyed listening to it.
