Soot on her Skin. Sons of the Crimson Earth, #2

Arabella Thorne has made her choice. She's not going back. Starving, hunted, and riding with the most wanted gang in Texas, the former heiress has swapped silk for denim and afternoon tea for loaded revolvers. But freedom costs more than she imagined-and the money is running out fast. When opportunity knocks in the form of a reckless gamble that could set them up for life, Cal Vance assembles the most unlikely crew the frontier has ever seen: a silver-tongued card sharp, a half-mad explosives man, and a society girl who refuses to stay in the background.
The plan is insane. The stakes are everything. Meanwhile, Arabella is changing-shedding the last traces of the woman she was raised to be and discovering strengths she never knew she had. So is the world around her. Old loyalties are tested, unexpected bonds form in the strangest places, and not everyone in the gang is who they seem. And far behind them, powerful men with deep pockets and cold eyes are already on the hunt.
The dust settled on her lips. Now the soot is under her skin-and it's never coming off.
