Miles, Mutants & Microbes

Two complete novels and a short novel in one large volume:
Falling Free - a Nebula Award-winning novel. Safety Regs wasn't just the rule book engineer Leo Graf swore by; he'd helped write it. But all that changed on his assignment to the Cay Habitat. Leo was profoundly uneasy with the corporate exploitation of his bright new students, nicknamed the quaddies, children bio-engineered to function in zero gravity. Now that exploitation was turning into something much worse. Leo hadn't expected a challenge where the right thing to do was neither safe, nor in the rules. Leo Graf adopted 1000 quaddies - now he had to teach them to be free.
"Labyrinth" - When Miles Vorkosigan is captured while on a secret mission to a lawless world, his only hope of escape is an unlikely pair of allies: a quaddie and a teenage werewolf.
Diplomatic Immunity - Miles Vorkosigan and his wife were heading home for the births of their first children, but a major diplomatic disaster looms at Graf Station, colonized by the descendants of the original quaddies, and duty calls. There Miles finds old friends, new enemies, racial tensions, lies and deceptions, mysterious disappearances, and a lethal secret with wider consequences than even he can anticipate. The downside of being a troubleshooter comes when trouble starts shooting back.
