The Last Sentinel (Clayton White Book 2)

Clayton White, a former Secret Service agent, has left his dangerous career behind and is living at sea with his fiancée, the daughter of Vice President Alexander Hammond. Though their relationship was once adversarial, Clayton has made peace with the vice president. When their ship, the NOAAS Surveyor, comes under attack and the Second Lady is assassinated the same day, Hammond—who survived an assassination attempt—asks Clayton for help finding those responsible. Despite his reluctance to work with Hammond, whose history includes violence and unpredictability, Clayton agrees when his fiancée's safety becomes threatened. Clayton must confront both new and old enemies as he investigates. Unknown to him, a long-standing adversary has been waiting for this moment and now has him in their sights. This time, Clayton's mission extends beyond saving the world to protecting the woman he loves.
