Most of the story was unique because it takes place in the human body and most stories don't normal have the setting a human body
Its interesting because the characters Grant, Reid , Cora, Duval, and Owens have to fight off bacteria to get to the clot in general carter's body.
The team decides to take a complicated way of getting to the clot in carter's body by a making the team get into a submarine and making it small then going into the body of general carter.
The reason they couldn't perform a surgery is because they didn't want to risk damaging carter's brain.
One of the characters is not caring about saving carter and I will not tell you until you read the book.
These are the representations of the character's of fantastic voyage.
