Identity Crisis

The crew of the da Vinci returns to the run-down Hidalgo Station to collect Commander Sonya Gomez from a hard-earned shore leave, and instead finds the station seized by a hostage-taker issuing impossible demands. The twist: the culprit is Gomez herself, trapped alone in the control center with no way out and no way to convince her own shipmates she hasn't lost her mind. A Starfleet Corps of Engineers novella about proving your sanity when all the evidence points the other way.
