She's keeping a secret. And another one. Even a third.
She never knows when she's going to discover another- so she has to be pretty good at keeping them. Probably helps she keeps most of them in one place.
Oh- and she mustn't forget, there are some secrets that can't be relocated. Like her enemy. Or her other enemy.
Yet she must stay secret from all, even those she fights alongside.
She is, herself, a secret soldier.
And somepony's onto her.

A reimagining of Secret Search, in which she actually demonstrates (some of) the skills necessary to keep so many secrets. I'm not perfect, though, so I'll probably mess up somehow. We'll find out.

Tags may be updated as the story progresses.

Would have been cancelled for no plot, but it's an indefinite hiatus instead because of the good start. I'll probably return to it someday, rewrite the latter parts, and continue- but I can't think of anything for that now.
