The time of reckoning for twins Hunter and Mercy Goode is here. The sisters are the latest witches from a long line of guardians in their family who protect the earthly gates to the Underworlds of various mythologies. But the gates have been growing weaker since the death of their mother, and they still have no concrete plan for how to heal them. Now Mercy, trapped in the ancient Egyptian Underworld alongside its protector, Khenti, is relying on her sister to help her. Meanwhile, Hunter is reeling from her power-hungry choices and also dealing with Amphitrite, the goddess of the sea, who is a growing threat to their hometown. But before they can save the gates and the citizens of Goodeville from further harm, the sisters first need to mend their broken relationship and find out why it is that their magic is not working to its full potential. This final entry in the Sisters of Salem trilogy examines the relationship between Mercy and Hunter as well as their empowering growth, which also means being held accountable for some terrible choices they made in Omens Bite (2022). But there are many open threads that need closure before the grand finale, some of them involving terrible and potentially fatal dangers, and they lead to an ending that is as bittersweet as it is unsatisfyingly hurried. The twins are White. A rushed ending to a witchy trilogy. (map) (Fantasy. 14-18) Copyright (c) Kirkus Reviews, used with permission.
