Abyss

In 2010's The Cabal, former CIA director Kirk McGarvey suffered the loss of his immediate family. His CIA agent son-in-law, Todd, was murdered, then McGarvey's wife and daughter were killed by an IED that exploded at Todd's Arlington Cemetery funeral. After avenging their deaths, McGarvey retreated to a lonely island to grieve. Now, in Hagberg's solid if overlong 15th Kirk McGarvey adventure, McGarvey, who was once a CIA assassin, is back in the real world helping train others in the deadly arts. When villains sabotage a science experiment involving giant undersea impellers able to generate enough electricity to do away with America's reliance on foreign oil, McGarvey investigates. This new technology, developed by Dr. Eve Larsen, threatens to economically gut the world's oil producers, so trouble is in store for Eve, and only McGarvey can keep her and her innovative technology alive. Readers will cheer as the doughty McGarvey puts aside his personal problems, shoulders the load, and soldiers on. (June)
