Lost Fleet Dauntless is bassically about a guy, Captain Jack Geary, who wound up floating in an escape pod for 100 years after being attacked by an alien foe. When he's finally rescued, he comes to find that he has actually been made into a fantastic hero for his amazing "last" battle, which saved hundreds of lives.
That for me was actually the coolest part of this entire novel: a galacticly historic celebrity, dumped into the laps of his adoring future public. It was a really inventive idea to have a reluctant hero, who actually can't stand the admiration and worship of his peers for something that, to him, hapened only weeks ago. For the marines and captains and starship fighters, the ledgend of 'Black Jack' Geary has given them hope and courage to fight their enemy for over a century.
I recommend this to those who enjoy the rough edged hero, and a fast paced, battle heavey space opera.
