Two Twins, One Corpse
She's fine. Probably. The twins are still arguing about it.
Lacuna Station is a relay and a biology lab circling a gas giant, resupplied every ninety days by an automated shuttle. You arrive as the new systems technician. The first voices you hear over the radio belong to two women arguing about the last tube of ramen. Your predecessor left after three weeks, with a note: Good luck. Don't touch Gerald.
Vera, the engineer, fixes everything and distils something unlicensed behind the reactor. Noa, the biologist, takes notes on everything, including you. They are identical twins and have never agreed on anything. Then a signal leads to a wreck, and the wreck holds one lifepod with one survivor named Yuki, who remembers her name and nothing else. Everyone has a theory about Yuki. You are the one who talks to her.
