Russia, 1881. The old world is trembling.
Elizaveta Georgievna Barvoskaya has known only privilege. But something has been loosening in her since childhood: a thread pulled free by the lives she glimpsed beyond her own.
When she joins the revolutionary underground, she moves into a world of safe houses, coded messages, and people willing to die for an idea. Among them is Sasha, brilliant, driven, marked by a past that shadows everything he touches, and something else she had not anticipated: the possibility of becoming, at last, entirely herself. But the underground is not a place of abstractions. It is dangerous, unforgiving, and moving with terrible purpose toward a single act that will change the course of Russian history.
Set against the darkening world of Tsarist Russia, The Rim of the Sky is a novel of extraordinary moral intelligence. It asks what it costs to act on what you believe, and what it costs not to.
