They say, "Never work with androids or children."

Quirk had one job to do, deliver papers to a Milan mafia boss, before leaving Earth for his home in the asteroids. But that was before being tailed, poisoned—oh, yes—and hijacked into raising foulmouthed fourteen-year-old convent girl Angelika Moratti, aka Moth, who'd rather see him asphyxiate in space.

Fleeing assassins, Quirk, Moth and her syRen® android S-0778 ride the space elevator to the Moon, where Quirk hires on to hunt an ex-terra-former who somehow used an android to murder his doctor. But which android of the two hundred under Lunaville's dome? The trail of bodies grows, time is running out; the only way they can save the dome and the two thousand souls beneath it is to solve The Mandroid Murders.
