Query: A jumpy, misguided attempt at a medical novel.

As a medical student, I've spent an awful lot of time in similar situations as the characters of this book, and I must say that the author describes them poorly. The story is less believable than it could be. It lacks the necessary explanation and description for the way the characters interact. Another major problem is that the story jumps around violently and the characters flip sides too quickly. The problems found in the begining resolve way too easily in the end. It's almost as if the author and editor were rushed to get this novel done. This idea is supported by the glaring spelling errors I found while reading. Not that I'm perfect and never misspell words, but it helps to show that the effort put into this novel was less than it should be. I am disappointed.
