I respect you far too much to think that empty pride is the only motivator you could call on. I think what you call pride is something much more than that. Belief in yourselves, perhaps, or perseverance in the face of adversity. Those are things to be proud of. That’s not the same as being proud. (Admiral Geary)
What is special about Geary is that he was found by mistake, while in cryo-sleep, after about 100 years. The century-long war with Syndics made high losses in the ranks of officers and now almost everyone is getting experience and promotion in the field, making them losing organisational and team spirit skills. Here comes Black Jack Geary, who knows the old ways, and starts teaching the brave, but rash, commanders how it’s done.
This is the first book in a series called the Lost Fleet, which has several other expansions as well. The author, under the pen name Jack Campbell, is a former US Marine.
The book has everything you can expect from a classic military scifi: space ships, Marines, ship to ship engagements, alien words, faster-than-light transportation. This particular book has little politics, just some jockeying for positions, or psychological considerations. It is clear cut, focusing a lot on dialogue, which is quite good, and dynamic space battles.
