Stay

After being discovered on a damp night, crying on a stone street with no other family, a wizard took Thana under his wing. He began training her and adopted many other kids in her lifetime, polishing them into desirable pawns. He was all Thana ever had, and everything she knew revolved around him. She had just turned 16 when a new arrival would shake the course of her dystopian world. Number 9 was his name, and he knew a lot more about Thana than the girl ever did. Even after learning the truth about what she really is and straying on another path, there are many dangers lurking in their wake. Can she fend for herself when everybody seems to be after her blood?

(I suck at descriptions. Just read the book lol)
