The Dead Cat Tail Assassins are not cats. Nor do they have tails. But they are most assuredly dead. Nebula and Alex Award winner P. Djèlí Clark introduces a brand-new world and a fantastical city full of gods and assassins.

All across the world, people look up at the moon and dream of gods. Gods of knowledge and wisdom, gods of tides and longevity. Over time, some of these moon gods incarnated into the human world alongside the other manifest natural concepts. Their job is to cross the sky above the Impossible City—the heart of all creation—to keep it connected to reality. And someone is killing them. There are so many of them that it's easy for a few disappearances to slip through the cracks. But they aren't limitless.

A young royal from the far north, is sent south for a political marriage in an empire reminiscent of imperial China. Her brothers are dead, her armies and their war mammoths long defeated and caged behind their borders. Alone and sometimes reviled, she must choose her allies carefully. Rabbit, a handmaiden, sold by her parents to the palace for the lack of five baskets of dye, befriends the emperor's lonely new wife and gets more than she bargained for.

But, trapped in a loveless marriage to a policeman who uses a microchip to monitor her every move, Nelah’s perfect life is precarious. After a drug-fueled evening culminates in an eerie car accident, Nelah commits a desperate crime and buries the body, daring to hope that she can keep one last secret.

Psychologist Dr. Ophelia Bray has dedicated her life to the study and prevention of ERS—a space-based condition most famous for a case that resulted in the brutal murders of twenty-nine people. When she's assigned to a small exploration crew, she's eager to make a difference. But as they begin to establish residency on an abandoned planet, it becomes clear that crew is hiding something. While Ophelia focuses on her new role, her crewmates are far more interested in investigating the eerie, ancient planet and unraveling the mystery behind the previous colonizer's hasty departure.
