I like these books for the amalgam between science fiction technology and an old fashioned sailing ship and British Empire universe. Carew is a great character and the stories are good old-fashioned pirates of the seas adventures. The kind where you would expect Erol Flynn or Burt Lancaster come swinging from mast to mast.
It is somewhat difficult to review these books since, in a way, they are very similar to each other in the way each episode of A-team or MacGyver or any other such like TV-show is, in a way, similar. Cain just gets a new problem to solve each time. As usual the solution involves liberal application of violence and if violence do not solve the problem you use more violence. Thus when you have reviewed the first couple of book it becomes difficult to write something new.
