The House of Duquesne is the action packed fourth installment in the Blanchard Witches series, delivering a powerful blend of intrigue, suspense, and epic supernatural combat. The Blanchard family, reeling from recent tragedies, is thrust into new turmoil when Tess, Trix, and Echo—the triplets newly welcomed into the family—encounter their estranged and dangerous uncle, Thaddeuss D'Angelo. A shadowy figure with ties to the ominous House of Duquesne, Thaddeuss brings dark secrets to light, forcing the triplets' mother, Blackie, to confront a haunting past she would rather keep buried. As Thaddeuss' agenda unfolds, Artemis struggles to maintain unity within the coven, while Seth grapples with grief following the loss of his wife, Yasmine. The Blanchards must uncover the sinister truths about the D'Angelo clan and how their fates, and the safety of the world itself, are intertwined. With alliances fraying and old wounds reopening, it will require unity and sacrifice to survive when the Blanchards are drawn into an epic showdown fought on enemy ground—and not everyone will make it out alive.
