Ren is a liar and a thief, a pattern-reader and a daughter of no clan. Raised in the slums of Nadezra, she fled that world to save her sister. Now, she has returned with one goal: to trick her way into a noble house, securing her fortune and her sister's future.

But in the city of dreams, her masquerade is just one of many. Enigmatic crime lord Derossi Vargo, stony captain of the guard Grey Serrado, dashing heir Leato Traementis, and the legendary vigilante known as the Rook all have secrets that could unravel her own.

And as corrupt nightmare magic begins to weave its way through the city of dreams, the poisonous feuds of its aristocrats and the shadowy dangers of its impoverished underbelly become tangled--with Ren at their heart.
