Follow the journey of the ever-curious twins Sola and Luna as they accompany their all-knowing mentor and ancient adventurer Lucius on his journey to discover the paradise on the other side of the world, where they will learn the secret named all that there is to know.

This whimsical mathematical fantasy story is a first in the history of mathematics fiction. It attempts to showcase the joy of solving challenging mathematical puzzles embedded within the narrative of a medieval fantasy epic that tries to answer the titular question:

“What is all that there is to know?”

The book follows a unique dialogue and discovery-based approach to learning that transforms our twin protagonists from unknowing novice learners to capable problem-solvers, all while assuming zero knowledge of mathematics and logic from the reader.
