Though Erin Baker is no long with the Agency, they come to her for another mission. This time it is to join a medical aid organization that may not be on the up-and-up. This will involve her heading to one of its offices, in Cuba, and dealing with its head physician, Emilio Diaz, who is her estranged father. Baker will find her desire to trust her father will go against her training and if she should choose wrong, a lot of people around the globe could suffer.
