When she's finally sent away to boarding school in London, she's happy to enter the brightly lit world of society girls and their wealthy suitors. Yet there are shadows there, too. Many of the men that try to charm Adele's new friends do so with dark intentions. After a violent assault, she turns to a roguish young con woman for help. Together, they become vigilantes meting out justice. But can Adele save herself from the same fate as those she protects? With a queer romance at its heart, this lush historical thriller offers readers an irresistible mix of vengeance and empowerment.
