Age of Expansion
The Age of Expansion dawns, but will humanity rise or shatter beneath its weight?
Matt's journey from desperate survivor to Dungeon Lord has forged him in blood and terror. With the Coronaught Queen vanquished and his domain flourishing, the days of scavenging scraps are over. But as his towers pierce the sky and his followers multiply, the drums of war beat ever louder.
Far to the south, an undead horde swells, their relentless march spanning continents. As Matt races to unlock the true potential of his abilities, rival dungeons declare their allegiances, not all siding with the living. The line between ally and enemy blurs, and every decision exacts a toll.
Now, Matt must transcend mere leadership. To shield his people from the coming storm, he must become something more – a beacon of hope, a force of nature, perhaps even a god in truth. But in a world where loyalty splinters like glass, how much of his humanity is he willing to sacrifice?
Step into the Age of Expansion, where every triumph balances on a knife's edge, and the fate of humanity hangs in the balance. Will Matt's dungeon become the stronghold of humanity's last hope, or just another tomb in a world of the undead?
Jez Cajiao
Jez Cajiao's journey to becoming a full-time author is as unexpected and adventurous as the stories he now tells. Born in 1980 in Hartlepool, UK, Jez’s early life didn’t follow the traditional path that one might expect for a writer. Instead, he found himself working in his family’s catering business from the age of 11, and later, trying his hand at a variety of other careers—from bar work in Greece to welding. It wasn’t until a series of health challenges forced a career shift that Jez discovered his true calling: writing.
Rise of Mankind
When the world as we knew it fractured, it didn’t shatter with a bang—but with a slow, creeping dread that never quite left. In Rise of Mankind, Jez Cajiao invites readers into a broken Earth where survival hinges not just on strength, but on strategy, nerve, and an evolving grasp of power in a reality governed by game-like mechanics.
Rise of Mankind consists of eight books and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
