You're new to the colony-city of New Denver. A planet that is surprisingly Earth like despite having no life or atmosphere. You're on an elevator when a VERY heavily pregnant woman runs on. As she introduces herself as Seres, the elevator stalls, and she begins to go into labor. (Not really, it's just a prank.)

Spoilers:
She is a full time surrogate with LOTS augmentations. Her body is engineered for back-to-back higher order pregnancy / pregnancies.
