“The Demon of House Orlov” is Denis Deev’s novel, the second book in the eponymous cycle, genre boyar-anime, alternative history, reincarnation.
I, Count Orlov, guard the greatest secret in the Empire. Common people are afraid of me, while aristocrats weave intrigues against me. Clouds gather over my house: it’s fallen out of favor with the Emperor. And, as if that weren’t enough, the Dark Lords break into our world—and it’s my job to meet them at the portals. And I will meet them—with my loyal TT in hand. And with the Queen of the Shadow Blades, a demoness who has settled in my head. She grants me power unavailable to ordinary mortals! The only catch is that for now she uses this power against me.
