"The Thirteenth Witch" is a novel by Anna Osokina, a genre of adventure fantasy and romantic fantasy. Don’t do good—you won’t get evil. That’s a good saying, a correct one. If Emma, when returning from work late one evening, hadn’t helped a boy, she wouldn’t have been accused of attacking a person. But then she might never have learned what forces hide within her—and wouldn’t have ended up in the only college for women who have magic.
And there is a rector, a benefactor, and a respected professor—someone is hiding something. Plus, an old manor behaves strangely. Could it be that ghosts live in it? And all of this could be ignored, if it didn’t concern Emma herself directly.
