The Elder Races by Thea Harrison is one of my favorite paranormal romances series, I love the full length books (especially the first few + the latest) but I'm still not sure how I feel about the novellas -most kind of seem hit or miss for me. And I was so sure that I was going to love this one, but instead I feel like I kind of got left hanging a bit. (view spoiler)[ Like another chapter at the end, or even a conversation where they worked out some issues before they rode off into the sunset would have been nice, or something else along those lines . . . I mean I got to the end and I was like 'Wait? What? But I want to know more..' (hide spoiler)] 
 However, Natural Evil is just a novella not a full length novel so its length can make comparisons with the longer works in the series a bit tricky. One thing that I love about the novellas that I have read so far is the diversity of characters and issues in them; humans and wyr and other magical people of all ages from all different walks of life. The tarot deck is especially interesting too - I know I'm reading the novellas out of order but I would like to go back and read everything (both the novels and novellas) in order and really see this deck pass from hand to hand. 
 Claudia's strength and her history really stood out to me in terms of characterization, I thought both of these were really well done for such a short about of space. And I thought the relationship between her and Luis was built fairly well even if I did want something more at the end. 
 Overall I really enjoyed reading this story and look forward to reading more by Thea Harrison.
