I could start by saying the Russians are after Bric, but that wouldn't be a surprise as the Russians are always after Bric. After killing him and Karen off a couple times and getting new identities in the Witness Protection Program, they take off in an RV to see the sights. It isn't safe for them in Key West and even his family thinks Bric is dead. After living life on the water, an RV just isn't going to do it so they "trade" it in for a yacht. This works well until the Russians find them, in spite of the new names. Seems to be a lot of leaks in the CIA. All of the books in this series have been loaded with action and this one is no exception.
