Something Dark and Holy Books in Order

Something Dark and Holy begins in a winter-soaked world shaped by saints, blood magic, and a long war between Kalyazin and Tranavia. It has the scale of epic fantasy, but it stays close to a small cast of characters who are frightened, stubborn, and rarely sure they are doing the right thing.

At the center is Nadya, a monastery-raised cleric who can speak to all the gods, not just one. Her faith is supposed to make her a weapon for Kalyazin, but once the war crashes into her home, she is forced into uneasy alliances with people from the enemy side. She wants to save her country, yet the closer she gets to the truth, the harder it becomes to tell who is holy, who is monstrous, and whether those are even separate categories.

Nobody in this trilogy gets to stay simple for long.

The other two key players are Prince Serefin Meleski of Tranavia and the blood mage Malachiasz Czechowicz. Serefin is trying to survive court politics, family pressure, and the damage war keeps doing to everyone around him. Malachiasz is secretive, ambitious, and dangerous from the start, but he is also one of the reasons the series never settles into a neat good-versus-evil shape. Much of the pull of the books comes from the tension between these three characters, which mixes mistrust, need, and attraction in ways that keep shifting.

The setting matters a lot. Duncan builds a world that feels cold, religious, and haunted, with ruined monasteries, uneasy courts, old texts, and magic that always seems to ask for a price. The books draw on Russian and Polish folklore for mood and texture, but the story is very much its own thing. One of the strongest threads running through the trilogy is faith and doubt, not just in the gods, but in countries, leaders, and the stories people tell themselves about duty.

And yes, it gets weirder as it goes.

As the series moves from Wicked Saints to Ruthless Gods and Blessed Monsters, the scope widens from wartime intrigue into something stranger and more unsettling. The horror element gets stronger, the gods feel less distant, and the stakes stop being only about ending one war. Even with all the divine chaos, the books stay character-first. If you like Gothic YA fantasy with dangerous magic, broken alliances, and leads who keep having to choose between devotion, survival, and each other, this trilogy is very easy to sink into.
