From the New York Times-bestselling author of We Hunt the Flame comes the first book in a hotly-anticipated fantasy duology teeming with romance and revenge, led by an orphan girl willing to do whatever it takes to save her self-made kingdom.

On the streets of White Roaring, Arthie Casimir is a criminal mastermind and collector of secrets. Her prestigious tearoom transforms into an illegal bloodhouse by night, catering to the vampires feared by society. But when her establishment is threatened, Arthie is forced to strike an unlikely deal with an alluring adversary to save it-she can't do the job alone.

Calling on some of the city's most skilled outcasts, Arthie hatches a plan to infiltrate the sinister, glittering vampire society known as the Athereum. But not everyone in her ragtag crew is on her side, and as the truth behind the heist unfolds, Arthie finds herself in the midst of a conspiracy that will threaten the world as she knows it. Dark, action-packed, and swoonworthy, this is Hafsah Faizal better than ever.
