Firebird

Natasha Trace is used to being marveled and stared at. She's the only woman in her flight class. For the most part, the staring only leads to occasional requests to join the remainder of her cohort for drinks at the nearest bar to base. She always refuses. Her COs have enough to say about her without resorting to the usual criticisms of her gender, which going to a bar would garner.

But Natasha's only human. When she seeks out a bar to get drunk where nobody knows her name, she's surprised to find the one man she never wanted to see off base dropping into the seat next to her. The conversation that follows changes her life and gives her a callsign.
