A collection of three separate stories connected by the framework of each story being a test of humanity by the galactic Watchers.

In "The Martyr," humanity deals with the unintended consequences of bestowing near-immortality on its best and brightest individuals.

In "Psi High," humans with psionic powers are social pariahs until a telepathic alien is discovered to be loose on Earth as a precursor to a takeover.

In "Mirror, Mirror," humanity is in an unusual psychological war with an elusive enemy.
