Publisher's Summary

The Year is 2040.
The Marines have landed on Mars to guard the unearthed secrets of an ancient and dangerous alien race: Ourselves.
Scientists have discovered something astonishing in the subterranean ruins of a sprawling Martian city: startling evidence of an alternative history that threatens to split humanity into opposing factions and plunge the Earth into chaos and war. The USMC -- a branch of a military considered, until just recently, to be obsolete -- has dispatched the Marine Mars Expeditionary Force, a thirty-man weapons platoon, to the Red Planet to protect American civilians and interest with lethal force if necessary.
Because great powers are willing to devastate a world in order to keep an ancient secret buried. Because something that was hidden in the Martian dust for half a million years has just been unearthed . . . something that calls into question every belief that forms the delicate foundation of civilization . . .
Something inexplicably human.

Fun space opera

If you like space opera this one is fun. Douglas puts an interesting twist on the future as the US gets a substantial dose of its own real politik. There are a lot of classic plot lines and good characterization for this genre. Definitely worth it.

I enjoyed this book...

What did you love best about Semper Mars?

Always in the first book of the series it takes time to get all the players down... About midway through the book I was into the story... Thanks for the adventure and I will be downloading book 2 and 3
