She was born to kill, born to die.   Crescent is a crowhopper — a genetically modified mercenary programmed for ruthless warfare. When she’s taken prisoner by Crater Trueblood instead of being killed in battle, she thinks it’s a disaster.   Crater is weary of war. He’s a miner, not a soldier. He’d rather be mining Helium-3 than battling the infernal crowhoppers. But after he captures Crescent and brings her to Moontown, he’s surprised how much he enjoys her company. When she’s falsely accused of murder, he becomes an outlaw to help her escape.   The unlikely pair escape into the “big suck” and wind up trekking with a caravan of mining pioneers toward a lunar ghost town called Endless Dust. To survive, they must do more than navigate the beautiful, desolate moonscape and battle a persistent band of crowhoppers sent to capture or kill them. They must decide what — and who — is truly worth fighting for.
