" Clive Cussler and his collaborator Paul do a good job on this book which has the usual amount of suspense and action. I have adjusted to Kurt Austin as the hero, having enjoyed reading about Dirk Pitt for years. Dr. Song Lee, the Chinese doctor and researcher makes a nice addition to the cast of characters, including Joe Zavala and the Trouts, Paul and Gamay. A pandemic is looming on the horizon, and the antidote needs to be completed and quickly transported to China, where it is going to start. Medusa refers to the source of the vaccine. Will they do it in time, despite the despicable villains? "
