What happens to a good person when survival requires embracing darkness? From aristocrat to assassin, in a world of moral ambiguity, Ada must find her humanity. Born to wealth, she is destined for a life comfort, yet she yearns for the one thing money cannot buy–freedom. A series of seemingly supernatural events deliver her from the mundane, but no one could have predicted the darkness that comes with it. Taken in and raised by a secret society, she is groomed as an assassin. As she comes of age, she must target the very aristocrats she once called kin, or attempt a daring escape. But if she leaves, she risks the lives of the two she loves most… her adopted sister and her enigmatic captor. A cross-genre blend of historical fantasy, steampunk, and coming-of-age, SHADOW RUNNER is a riveting saga of sacrifice, betrayal, and redemption that will leave readers on the edge of their seats.
