I am not going to rehash the blurb, so please consider that for context. It provides a solid summary of the plot
I thought that I would be much more uncomfortable with this relationship that I was. Admittedly, I know little about to Tourrette Syndrome or brain damage and its effects, so I find it challenging to comment on the appropriateness of the relationship between the two main characters. All I can say, is I initially saw Ethan as stunted in mental maturity, but came to see him as a mature man with certain limitations.
Given that, I very much enjoyed the story and thought it was rather sweet. :)
