World Affinity: The Radiant Traveler Series, Book 4

by R.A. Schmitt, Reuben Ashcroft (Narrator)

Callum and his friends find themselves in a land once part of the mainland, now separated by the Shallow Sea and ruled in part by the Principal Cleric’s Order. Here, ancient ruins whisper of forgotten Systems, and the team begins to piece together fragments of the world’s oldest pasts.

After the coronation of the clans, their journey leads them beyond familiar shores to islands where storms walk like beasts, spirits test the living, and the Trickster’s influence twists the laws of magic and truth. What begins as exploration soon becomes survival, as the dungeon beneath these islands remembers every lie ever told.

For Callum, it’s a chance to master his Tier Two powers and uncover the meaning of the Celestial Echoes calling his name. For Olivia and Auggie, it’s a race to keep the group alive when even the System itself can’t be trusted.
