In the riveting final volume of Zoe Marriott’s urban fantasy trilogy, all hell is breaking loose in London. Literally.

It’s been a long few days since Mio stole the ancient, magical katana from her family’s attic. She and her friends have defeated the demonic Nekomata and banished the Goddess of Death’s plague-spreading Shikome. But at a terrible cost: Mio’s beloved Shinobu is lost to her, imprisoned again within the katana. With no time to succumb to guilt and grief, Mio must find a way to defeat the vengeful gods Izanagi and Izanami once and for all. Her only hope lies in the one place immortals can’t go: the realm of dreams, a shifting dimension of water and ice, echoes and memories, beauty and danger.
