Lost Fleet: Fearless (Lost Fleet Series #2), Vol. 2 by Jack Campbell
Yes. No disappointment in this series - the second installment is great, and develops the complex situation of John Geary and his leading of "The Lost Fleet" against impossible odds.
The Barnes & Noble Review
A centuries-old interstellar conflict. Millions dead. Entire star systems obliterated. A tough-as-nails leader trying to lead a lost fleet back home from deep in enemy territory. Military science fiction fans who are searching for a fast-paced, no-holds-barred, deep-space military-powered adventure should check out the Lost Fleet saga by Jack Campbell (pseudonym for veteran genre writer John G. Hemry), a surprisingly multi-layered series that incorporates elements of space opera, apocalyptic thriller, and, at times, subtly allegorical social commentary.
In Fearless, the sequel to 2006's Dauntless, legendary war hero Captain John "Black Jack" Geary is once again faced with a seemingly hopeless situation. Recently rescued from an escape pod found floating in space after nearly a century in suspended animation, Geary is desperately trying to find a way to bring what's left of the Alliance fleet back home. In his possession is a device acquired from an enemy starship that could end the war forever. But with the entire military force of the Syndicate Worlds hot on his trail, Geary is up against impossible odds -- especially when he frees a labor camp of Alliance POWs and rescues an egomaniacal captain whose irrational machismo could doom the entire fleet… ....
I do think this compares (favorably) to the Miles Vorkosigan series. The hero is likewise a gifted leader, whose tactical skill is balanced by an interior skepticism and honor that keep him from being a "mere hero." I've got book number three ("Courageous" - all ship names in his fleet, by the way) in hand from the library, and bought number four ("Valiant") for an upcoming trip. It will be tempting (but I'll resist) to read it as soon as I finish number three.
