Liberty's Crusade (StarCraft, Book 1)

Far in the future, 60,000 light-years from Earth, a loose confederacy of Terran exiles is locked in battle with the enigmatic Protoss and the ruthless Zerg Swarm. Each species struggles to ensure its own survival among the stars in a war that will herald the beginning of mankind's greatest chapter -- or foretell its violent, bloody end.
Danny Liberty was a good reporter...too good. When his investigations struck too close to the heart of the corrupt Terran Confederacy, he faced a simple choice: continue his current series of exposés, or take a hazardous new assignment covering the Marines on the front lines of the Koprulu Sector. It didn't take him long to decide....
Behind the attacks of the Zerg and the Protoss lies the story of a lifetime, but every piece of information blurs the mystery further. Thrown into the middle of a war where the outcome will determine mankind's very survival, the only thing that Danny Liberty knows for sure is that the only person he can trust to keep him alive is himself.
