When the phantom of Marie Laveau appears and a wave of violent killings spreads through New Orleans, Thea Blackwood finds herself facing one of the most dangerous supernatural mysteries of her life. But the greatest threat may not be the phantom itself.
Mia, Thea’s closest friend, becomes entangled in Marie’s curse, forcing Thea into an impossible position: save her friend without destroying the person she loves.
Then Mother Folsom reveals her true intentions.
For months, she has been manipulating events from the shadows, using Thea, Mia, and the chaos surrounding Marie to get closer to a mysterious black box. She believes Marie’s power is the key to opening it—and she will sacrifice anyone necessary to obtain what lies within.
Thea must fight through fear, grief, betrayal, and overwhelming magical power while Brandon and the others race to stop Folsom.
But when Thea finally discovers what her enemies are willing to sacrifice for knowledge, she faces a choice that will define everything she becomes.
Sometimes the most powerful magic is knowing what not to take.
