After the vampires shatter their fragile treaty with the humans, a day of reckoning dawns. Betrayed by the bloodthirsty fiends that enslave their people, the human lords rally a militia to strike back. Shanda, a mayor's tomboyish daughter, is unexpectedly thrust into a leadership role. But it's a role she doesn't want, and she certainly isn't prepared for it! How can she possibly lead a militia?

Meanwhile, the violet maid has seemingly vanished, and the stakes have never been higher. If King Isaak finds Lady Adeline, the consequences could bring about the end of the world. With that threat looming, have the humans taken on more than they can handle? And what has become of Oskar, the fiendish vampire prince?

In The Only Lady Knight, the second installment of Dark Kingdom, love blossoms, heroes are tested, and worlds crumble.
