Caliban's War (Expanse, #2)

by James S.A. Corey

If Earth decided it needed Ganymede all to itself, four grunts walking around the greenhouse dome wouldn’t stop them. With dozens of Earth and Mars warships in a tense standoff in orbit, if hostilities broke out the ground pounders would probably find out only when the surface bombardment began. To her left, the dome rose to almost half a kilometer: triangular glass panels separated by gleaming copper-colored struts that turned the entire structure into a massive Faraday cage. Bobbie had never been inside one of the greenhouse domes. She’d been sent out from Mars as part of a surge in troops to the outer planets and had been walking patrols on the surface almost since day one. Ganymede to her was a spaceport, a small Marine base, and the even smaller guard outpost she currently called home.
