The Lost Fleet delivers thrilling combat on a grand space-opera scale. Now Admiral John "Black Jack" Geary embarks on a brand new mission - to defend the Alliance from itself - in New York Times best-selling author Jack Campbell's latest action-packed novel....
Two Syndicate World star systems have fallen prey to a mysterious fleet of warships - a fleet controlled entirely by artificial intelligence - that is now targeting Alliance space. The warships are no mystery to Geary. They were developed by his government to ensure security but malfunctioned. If the Syndics learn the truth, the war with the Alliance will resume with a vengeance.
As the government attempts to conceal the existence of the AI warships - and its role in their creation - Geary pursues them, treading a fine line between mutiny and obedience. But it soon becomes clear that his fleet is no match for the firepower of the machine-piloted armada.
With the help of the Dancer species of aliens, Geary has tracked the AI ships to their secret base in the supposedly mythical Unity Alternate star system where his fleet, the last hope of the Alliance's future, will end the conflict at any cost....

Magnificent saga.

Great story with strong characters,very well constructed themes and edge of your seat action sequences. I gave it five stars as a good story arc, but I feel it has been left hanging a little, as now I think we need a trip to Unify to sort out the main theme of distrust and disaffection between the frontline officer Corp and the politicians. Room for one more book in this saga perhaps?

The Alliance Strikes Back!

This is perhaps one of the most poignant books in the series thus far. Yes as a wise man once said "Great men are forged in fire. It is the privilege of lesser men to light the flame. Whatever the cost." This time Geary and his closest must pay a high price to save the Alliance from itself.

Leviathan was brilliant. I loved every second, even the emotionally painful parts. I have been feverishly wanting a book that dealt with the political pieces of the Alliance. Boom, here it is! Yet every little twist and turn of the political knife could have jumped off the pages of today's newspapers. Political responsibility.. what is it? Who is responsible? Who holds the reigns?

I am disapointed that Mr. Hemry (Jack Campbell) no longer does the Audio introduction for each book... but that is such a small complaint against such brilliant writing. Thank you for giving us a quick peek into your imaginative world.

As always Christian Rummel personifies the people of this series. His work in bringing these characters to life has shown he is a master at his craft.

Just Brilliant.

Great Story/Conclusion?

Not certain if this is the end of the series or not but it does feel like there is closure here. More great detailed fleet battles against a very challenging enemy. I would love to get more details on certain detainees and factions in the alliance and to see what the outcome and fallout entail ultimately. Over all though another great Black Jack story!
