Freak of Nature was good. However, there were a few things that reduced my enjoyment of the story. 
 First of all, the relationship between Kaitlyn and Lucas felt unnatural. It was weird to me that Lucas looked at Kaitlyn as a science experiment for the most part. Even after they were dating, there were still instances where he said something that I felt was weird. For example, it was strange when Lucas said he had never thought to give her back her taste buds and thought she wouldn't need it. It showed how he still viewed her as less than human. Kaitlyn should have also been more upset about him trying to take her emotions away. 
 In general, some aspects of the story progressed too rapidly. Included in this was the relationship between Lucas and Kate. It seemed to progress at warp speed despite the obvious complication of Kate still adapting to the world around her and finding herself. In addition, the conclusion about Evan seemed anti-climatic. Sort of thrown in to bring an end to that direction of the story. Same can be said about when she came back and talked to Harrington. All these aspects of the story could have been better created to make more tension and suspense. Some more action thrown in wouldn't have gone amiss either. I wanted to see more evidence of her intelligence and maybe more use of her abilities. It might have given her a little more personality.
