Hope Rises by David Baldacci
This is the sequel to the compelling Nash Falls. Business executive Walter Nash is still recovering from the nightmare of the events of the first book, including the death of his beloved daughter. After undergoing a complete physical and attitudinal makeover, and becoming an FBI information, he sets out to take down the woman he holds responsible for all of his trouble, Victoria Steers. But she has other plans. It's a good follow-up to the first book and Walter/now Dillon Hope is a worthy hero.
