Ink Blood Sister Scribe

The Kalotay family has spent generations guarding a private collection of magical books, each written in human blood, each granting a single strange power to the reader who bleeds for it. After their father dies under circumstances that do not add up, Joanna stays behind to protect the library on an isolated property, warding the house and hiding from a world that would take the books by force. Her estranged half-sister Esther, meanwhile, keeps moving from country to country, unable to stay anywhere longer than a year because of a curse she does not fully understand. When a secretive society of collectors begins hunting the family's books, the sisters are forced back together to uncover the truth their parents buried. Törzs builds a hidden world of blood-written magic running beneath ordinary lives.
