Michael Keating is a former Navy SEAL -- and a former President of the United States.  Now relocated to rural New Hampshire,  all he wants is to have a normal family life..even though he is still surrounded by secret service agents.  But then a terrorist who is bent on revenge kidnaps his daughter.  He will have to pull in some favors and rely on his Seal training to try to rescue her since he is getting no help from the current President.  It is quite a thriller and I enjoyed it very much.
