Star Eater by Kerstin Hall

“As a member of the Sisterhood of Aytrium, Elfreda Raughn is part of a magical bloodline that preceded her, from her mother to her grandmother and generations back. But it is the same bloodline that forces Elfreda into eventual pregnancy and unavoidable death. Hoping for a way to escape her fate, Elfreda finds a mysterious group, those who believe the power of the Sisterhood has gone too far. Acting as their spy, Elfreda infiltrates a world of opulence and cunning, as drought and rationing affects the rest of Aytrium. With her closest friends by her side, Elfreda discovers that freedom could come at great cost, for the Sisterhood has made many sacrifices to keep its power, and Elfreda could find she is the next to pay. Systemic power structures built on the back of a dead god, ritualistic cannibalism, and magical disease are balanced with emotional themes of love and regret. VERDICT: Hall’s (The Border Keeper) solid worldbuilding and strong prose create an utterly gripping novel that blends the boundaries of horror and fantasy.” — Library Journal, Starred Review
