The shape of monsters

"Iriset-prodigy, outlaw, now sunderer-has broken the Moon-Eater god's prison at the heart of the empire. But the consequences of her actions land her in a city of monsters where the heretical magic of human architecture is freely practiced, and the only person she knows-and can trust-is Lyric, the emperor she's lied to and loved in equal measure. As scheming kings and capricious gods drive them towards different extremes, they soon realize that to find their way home, they must remake the world...at the risk of breaking it forever"-- Provided by publisher.
