Pilgrimess by Kara Reynolds
 
Robbie Finch and her found family of fellow lady criminals are weathering tyranny from a theocratic patriarchal rule. Word that her niece is in trouble interrupts their thriving resistance movement. Disguising themselves as penitents on a religious pilgrimage to a powerful enemy city, the ladies set out on a rescue mission. Along the way, lifelong enemies persecute them, an old flame reignites, and danger threatens. And a strange man will not stop dogging Robbie’s steps. As she and her mysterious new suitor dance around each other’s desires and intentions, Robbie is forced to reckon with her past. She can only defeat the evil that looms if she remembers who she is, what gift she possesses, and opens her heart to new kinds of magic.
