Robert Ludlum's The Janson Option

Reformed from his days of covert operations, Paul Janson has set a new mission for himself. Working in partnership with champion sharpshooter Jessica Kincaid, he rehabilitates disenchanted agents and helps them create new lives outside of the violent intelligence sector. Janson also takes on independent assignments - for a fee, he'll use his skills to resolve international crises. But only those that he believes contribute to the greater good of all. 

When oil executive Kingsman Helms begs Janson to rescue his wife, Allegra, from Somali pirates, Janson and Kincaid seize the opportunity. At last they can derail American Synergy Corporation's scheme to subvert sovereign nations into wholly owned subsidiaries. But the pirates are the least lethal threat in the violent chaos of oil-rich East Africa, and when Janson and Kincaid stumble into a bewildering storm of plots and counterplots, they begin to fear that the only way to escape would be to abandon the innocent Allegra.
