Carrick, M. A. Rook & rose #1

"Nightmares are creeping through the city of dreams... Renata Viraudax is a con artist who has come to the sparkling city of Nadezra -- the city of dreams -- with one goal: to trick her way into a noble house and secure her fortune and her sister's future. But as she's drawn into the elite world of House Traementis, she realizes her masquerade is just one of many surrounding her. And as corrupt magic begins to weave its way through Nadezra, the poisonous feuds of its aristocrats and the shadowy dangers of its impoverished underbelly become tangled -- with Ren at their heart."--
