OK, I see what people mean when they say that Davy is slightly conceited, but look where she comes from...but I like this book. It exposes human flaws in the form of Homicidal Tendency Syndrome. Personally, I believe that if all humans are imperfect and can be homicidal should they choose, every person in this book has HTS, technically. The characters like Gil, Sean, and Davy were just unfortunate to have the particular gene Wainworth blamed for HTS. That is my opinion, and I respect other opinions that disagree with my beliefs about this book.
