Query: Never ending Mutation

The book Mutation, the so called "Medical Thriller", was not so much a thriller. The main character, Dr. Frank decides to make the son of his dreams through invitro fertilization, but everything turns into a disaster. The book Mutation was too predictable. The reader knew what was going to happen after the first one hundred pages. The author, Robin Cook, used to many scientific words and went into scientific descriptions, which makes the reader curious as to what he is talking about. Although he had good description, it began to drag on. Cook's novel was an easy read, but not recommended for personal enjoyment.
