The Seventh Sister by Millie Abecassis

Seer Éliane is destined to a brilliant future as a servant of Aurië, the Sun-God. Everything changes when the High Seer, her superior, becomes jealous of Éliane's abilities and chases her from the temple. Having no family, Éliane has no choice but to find refuge in Sanctuary, the mysterious mansion of Lady of Clairemont, alongside six women living there as sisters and refugees. When the sisters begin to disappear, Éliane must find the truth about Sanctuary and its secretive owner before she disappears, too. A horrific retelling of Bluebeard and Snow White, The Seventh Sister is a tale about sisterhood and overcoming adversity.
