Jericho's Redemption by Mary Lynne Gibbs
Jericho returns to the Obsidian camp, only to learn that her sister Candace destroyed it as part of a plot to dismantle the resistance movement that brought down their mother, the High Priestess. The rest of the resistance blames Jericho for the deaths of their friends. Not only does Jericho now have to right the wrongs her sister has done, she must contend with a few guests to the camp who bring secrets that will change her life forever. Either she'll redeem herself in the eyes of her comrades, or she'll die trying.
