What would you do if you found the secret of a lifetime? What if you could change the universe? Chase Weston never would have thought being the bodyguard for an archaeologist would be so dangerous…even an archaeologist digging for the remains of an alien civilization on another planet. But everyone wants what Dr. Angel Cortez has found... no matter the human cost. Because beneath the dirt and stone lies an ancient mystery, a secret history, and a warning of an implacable alien enemy. And if the warnings are true, then corporate mercenaries and Sea Dragon commandoes are the least of Chase’s worries. Can Sgt. Chase Weston and Dr. Evangeline Cortez uncover the mystery of the Sunkillers? Or will they just be the latest to die trying?
