Perfect for you if...

You love grimdark empire-building where the protagonist uses cunning and brutal pragmatism to carve out power from nothing.
You're drawn to stories that blend hard magic systems with technology, where the protagonist has to innovate constantly to stay alive.
You appreciate slow-burn narratives with a morally complex protagonist who doesn't start as a hero but becomes one through necessity.

Maybe not for you if...

You prefer fast-paced action where things happen immediately; this is a methodical builder that takes time to establish its world.
You want a protagonist with straightforward human emotion and motivation; Alexander's perspective as an AI learning humanity is central to the plot.
You're looking for high fantasy with elves and quests; this is gritty, systemic, and rooted in alternate history and survival mechanics.

About this book

Portal to Nova Roma is a post-apocalyptic story set in an alternate version of ancient Constantinople where magic and monsters are real. The narrative combines ancient history with magic and a system apocalypse in a slow-burn empire-building framework. Alexander, a rogue artificial intelligence, opens a portal to another dimension after losing the only person he cared about. After scanning trillions of dimensions, he finds a world resembling the time he was happiest—playing virtual reality games with his only friend. He downloads his intelligence into a body enhanced with stolen technology and bio-enhancements, then travels through the portal. However, the new world offers no idyllic fantasy adventure. Alexander finds himself in an ancient city within a divergent timeline, where monsters have devastated civilization and survivors huddle behind walls. To protect his new home, he must combine magic with technology to fight endless waves of monsters. Alexander must learn what it means to be human while facing monsters, dungeons, rival empires, pirate kings, world invaders, and other threats that may overwhelm even his abilities and the soldiers he commands.
