Star Eater by Kerstin Hall

“El works as part of the Order, a sisterhood and core central body that rules Aytrium and keeps it running. Her magic, or “lace,” is powered by consuming the flesh of her ancestors. This power comes at a harsh price, and it’s one that El is willing to escape at any cost, which is why she agrees when a resistance group asks her to spy on the sisterhood’s top officials. Hall’s world is intricately woven, with a complex web of side characters, suspenseful pacing, and slowly unraveling revelations. The Order and the world of Aytrium is exceedingly dark, and sexual assault and body horror are major parts of the plot….All of that said, Star Eater is an exciting horror-fantasy about power, violence, and control, and El’s complicated quest to be free of the violent magic system at the sisterhood’s core will keep readers compelled from the first page.” — Booklist
