Bianca Monroe should be celebrating-she's just handfasted the love of her life, Merrick. But fate has other plans.

A summons from High Priestess Alina pulls Bianca to the Southern Network, where magicless witches are vanishing without a trace. To accept Alina's plea for help means defying the Central Network Council. To refuse could cost innocent lives.

When Council Member Georgette escalates her attacks against the Sisterhood, Bianca has had enough. Stripping away the Council's influence, she leads the Sisterhood into rebellion, setting them on a dangerous path that may cost them everything.

Meanwhile, her pursuit of the missing witches takes her to the Western Network, uncovering magic more ancient-and more perilous-than she ever imagined.

But Bianca is no stranger to loss. And this time, the battle is more personal than ever.
