Publisher's Summary

Vicious interstellar conflict with an indestructible alien species. Bloody civil war over the last habitable zones of the cosmos. Political unrest, militaristic police forces, dire threats to the solar system....
Humanity is on the ropes, and after years of fighting a two-front war with losing odds, so is Commonwealth Defense Corps officer Andrew Grayson. He dreams of dropping out of the service one day alongside his pilot girlfriend, but as warfare consumes entire planets and conditions on Earth deteriorate, he wonders if there will be anywhere left for them to go.
After surviving a disastrous spaceborne assault, Grayson is reassigned to a ship bound for a distant colony - and packed with malcontents and troublemakers. His most dangerous battle has just begun.
In this sequel to the best-selling Terms of Enlistment, a weary soldier must fight to prevent the downfall of his species...or bear witness to humanity’s last fleeting breaths.

Very good story with some bad physics

I find the story entertaining and engaging and I wish there was a third one out. There's always something going on or about to go on and yet the plot doesn't take you where you expect, it's always something slightly different, or radically different, from what you thought. The characters are believable and engaging. The side issue of Earth society is dealt with in a credible manner without becoming preachy or boring.

The reader is pretty good, but sometimes hard to tell men from women and too many people have the craggy "I shout for a living" voice even when talking to normal people. I worked with UK military for a long time and have US military friends (senior master sergeant, nuclear engineers, SEAL team commander, Ranger) and none of them had that ruined voice. Mostly I liked the performance though, 97%.

As science fiction if he wants a mega gun that can do what a tank gun does today but can be carried by a normal soldier I have no issue with that. Unlikely, or according to NASA this week, quite possible FTL drive... perfectly fine by me. And there's plenty of that. SciFi does not need to explain its physics and should not try.

Slight spoilers and complaints of poor research and physics from here...

Where it broke the suspension of disbelief for me was in the mundane physics. You don't need to be specific, you can say it's a micronuke and leave it at that.

If you are bothering to tell me the weight and speed of something please bother to work out your numbers credibly when you are putting them in the mouth of a physicist. 43,000 metric tons is 43x10^6 Kg, 5km/s is 5x10^6m/s. Energy is 1/2 mv^2 so .5x43E6x(5E6)^2 = 5.375E20J. As it happens there is a well known conversion factor for TNT equivalence so 1billion tons of TNT is 4.184E18J so the number you want is 128.5GT equivalent. Not vaguely hundreds. If the blast took place in one second then it is 5.4E20 Watts, the sun is 4E26 Watts, Just about 1,000,000 times the power, all the time. So at about 8.3 light minutes it would still just be a little flash. Not a second sun for some time. Not enough to bother sensors.

If a thing happens 150 million Km away and you are using optical sensors it will take 8.3 minutes for the light to get to you, not a few seconds.

If you blow up a ship its engines can no longer propel it, so it is not still accelerating at 0.25g.

A 50 microton warhead would be equivalent to 1.6oz of TNT. Why not just use 1oz of HMX and save the technical complexity. Of course that won't do what you said, but it's SciFi, feel free to make the warhead a more believable and credible size.

There were more, but those were the ones I found particularly offensively careless.

Is shit hole, one word or two? First of all, I hate to burst some bubbles, but this is not as good as book one. I was amazed that I listened to this right after listening to Forever War by Joe Haldeman. The future world that Kloos describes, sounds actually like Haldeman's future. Everyone lives on the dole, everyone gets paid in calories, everyone hires body guards and the army is full of idiots. Haldeman had more guns, but it looks like Kloos is headed that way. So, it is a liberal future, where everyone depends upon the government (and it is not good.) It is a conservative future where everyone owns a gun and it is not good.

The story starts out pretty good with these 80ft tall Aliens, who think we are just bugs. An interesting concern, especially when you considered how we treat anything smaller then us. They are in the very beginning and one of there ships is in the very ending, but between times our hero fights, the Russians, the Chinese and then his own country. I also find it unbelievable that a group of home troops who spend there careers killing North Americans, would all of a sudden grow a conscience when they go to another planet. I felt that there were too many conflicts, which made this too unbelievable. It is not a bad book and if you like Military Sci-Fi and you don't need it to make a lot of sense, then you will enjoy this.
