Anton is with the Night Watch, an organization of magically gifted beings who fight on the side of the Light; although there's only so much they're allowed to do, due to the treaty that maintains a balance with the forces of Darkness. I enjoyed this book until I googled the author, who's been virulently anti-Ukraine since at least the Euromaidan days. Very disappointing and surprising, given the book's humanity. At least I bought it at Goodwill.
