After Zoey Redbird and her friends banished Kalona and the fallen High Priestess Neferet from Tulsa, everyone would expect them to calm down a bit. But calmness is not in the program, as Zoey and Stark recover from their encounter with death and the fledgling vampires try to recover after the end of Neferet's reign of terror. Zoey feels haunted by her complicated bond with the ancient Cherokee A-ya, while Stevie Rae tries to manage the things she kept hidden from her best friend. However, when a mysterious threatening force lurking in the tunnels beneath Tulsa begins to spread and Stevie Rae refuses to reveal where she goes and what she does, Zoey starts to wonder to what extent she can trust the only person she has always considered an ally. Will their choices ultimately lead them to destruction and darkness envelop the House of Night?
