My summer reading plans went seriously bust due to lots and lots of home improvement work, but I still managed to finish off another book in the ever growing stack.  [amazon_link id=”0441017088″ target=”_blank” container=”” container_class=”” ]Relentless[/amazon_link] is the fifth book in Jack Campbell’s Lost Fleet series.  The action picks up right where book four ended, with the fleet getting closer to home but still fighting the Syndicated Worlds for every bit of progress.  The enemy in the shadows makes a slightly more visible appearance this time, which sets the stage for maybe another series?  I was surprised that he brought them home this early, but I see where the series and universe is going and will be putting book six on the stack soon.
