Age of Iron
Matt and Chris have made it home ahead of the Undead curse, but at what cost?
The Dungeon is surrounded, the refugees have made it to safety, but… they need food, water, space to recover and rest, and none of these things come cheap. That cost must be paid in mana.
Mike and Kelly were sent to bring reinforcements from the Park, but they’re walking into a meatgrinder, one that will strip the life from them, then raise them to besiege those they love…
Matt has only one chance… lead the refugees, forge them anew into a force that can face the undead, in their tens of thousands.
Worst of all… the beers damn well warm.
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.
