For the first few chapters I couldn't put this book down. The author knows flying and medicine and worked his knowledge into a tight plot about an Air Force Captain singled out for special ops who is sent to track down a scientist who stole some Ebola virus cultures from Africa and is being paid to develop it into a weaponized version and a vaccine to inoculate the unknown interests who hired him.
The locales swiftly change from Africa to an island in the Indian Ocean to S. Carolina to a yacht making its way to the Azores. Along the way, the Captain picks up some unlikely allies and villains such as a jailed banker, an oversexed female FBI agent, a female yacht owner who may be the mastermind and her boyfriend, a Scottish sailing master and an Azorean Air Force Colonel. These characters make the yacht voyage something of a cross between a WWE match and a group sex orgy until the real (?) villain appears and blows up the yacht after kidnapping the owner. Sometimes it takes a program to keep them all straight, but it is all good fun.
The action sequences are believable and for once you get a touch of realism where the hero gets seriously wounded,blown up and all the while in danger of contracting Ebola. People you learn to care for die in the violence. It's a healthy change from most books where the good guys win without serious consequences to themselves and their friends.
The plot has a good number of twists and turns and the final denouement which explains the plot is a complete surprise. I recommend this book as a good read if you enjoy the action thriller genre.
