Heroes of Another Age: A Guardian Prequel
Winner of the Literary Titans & Global Book Awards.
Hidden high in the mountains, twin brothers Aaron & Aton live quiet lives herding sheep and guarding their secret, that they’re werewolves. To the villagers below, shifters are monsters to be hunted. But when tragedy strikes, the twins learn the truth about who they are… and what they were born to do.
Long before they came into the world, Seers whispered of brothers marked by fate, one with incredible strength, and one who wielded magic, who would be destined to confront a darkness rising in the east. As their world begins to crumble, Aaron and Aton must leave their home and face the a journey across Eris to stop a catastrophe that could consume an entire city.
Their path will lead them through snow-covered mountains and dark forests filled with demons, in a land teeming with gods and ancient power. Aton’s courage and Aaron’s fragile gift will be tested as they discover that prophecy is not a promise — it’s a choice.
Brotherhood. Destiny. Quiet magic in a world on the brink.
If you love character-driven adventure, slow-burn stakes, and the heart of stories like His Dark Materials and Throne of Glass, step into Heroes of Another Age — and begin the journey that starts it all.
