Mist & Bone. Forest of Bones Univese

Zieka has always healed those who seek her services. When a wounded soldier drags an unconscious Luca to her doorstep, she finds herself embroiled in a battle between good and evil she never knew existed. Even as she joins the fight, her one wish is to regain her true name stolen by her self-appointed guardian, Chelim, a dark demon with their own hidden agenda. Between crossing realms with Luca to escape his pursuers, Zieka meets vampires, magicians, and Elder gods who all claim they will help her for something in return-her family book which contains the history of her line and all her healing recipes.
Chelim warns her against Luca and swears to protect her. However, Zieka seeks out an Elder god to unravel the mystery surrounding her book, losing her given name, how her awakened ability to cross worlds all fits together in the battle for the book and her soul. The truth will rattle her very existence, but she must stay strong to find the true villain who wishes her dead.
