While this is a novel written entirely in modern day English, there are a few extras that definitely lend credibility to the story. Amedeo Technologies is a firm that is chasing the next leap in science and internal medicine. With a formula called Proteus, Amedeo Technologies has developed the platform from which all future science in that area will be launched. Michael Connelly does a credible job of describing both the formula and its applications, taking into consideration the very real research going on in the world today.
