Guardian (The Lost Fleet) by Jack Campbell

Science Fiction/Space Opera

From Goodreads:

"Admiral Geary’s First Fleet of the Alliance has survived the journey deep into unexplored interstellar space, a voyage that led to the discovery of new alien species, including a new enemy and a possible ally. Now Geary’s mission is to ensure the safety of the Midway Star System, which has revolted against the Syndicate Worlds empire—an empire that is on the brink of collapse.

To complicate matters further, Geary also needs to return safely to Alliance space not only with representatives of the Dancers, an alien species, but also with Invincible, a captured warship that could possibly be the most valuable object in human history. Despite the peace treaty that Geary must adhere to at all costs, the Syndicate Worlds regime threatens to make the fleet’s journey back grueling and perilous.

And even if Geary escortsInvincibleand the Dancers’ representatives safely unharmed, the Syndics’ attempts to spread dissent and political unrest may have already sown the seeds of the Alliance’s destruction."

This is short and sweet this time.  I have followed this series from the beginning.  Guardian has the same cast of characters and is a continuation of the previous Lost Fleet Beyond the Frontier books.  Guardian is a good story but for me it lacked the tension that was part of the previous books in the series.  I could not tell from the ending if this was the last book in the series or if there will be more.  If there are more I will continue to read.  

I think reading this series from the start is the best way to know what is going on.
