The World Below Series

They thought they were just normal twins. Quiet. Geeky. A bit awkward at times. But on the morning of their sixteenth birthday, everything begins to change.

Their parents hand them weapons with no explanation. Strange abilities begin to surface. And a truth they were never told starts to unravel around them. Because in this world, being a twin means something far more dangerous than they ever imagined.

Thrown into a hidden world they didn’t even know existed, Ella and Kal are suddenly expected to become something they don’t feel ready for. And the bond they’ve always shared might be the only thing strong enough to survive what’s coming.

Twins of Fire is a coming-of-age YA fantasy series filled with Celtic-inspired mythology, emotional depth, and the powerful connection only siblings can share. Perfect for readers young and old who love adventure, other worlds, and just the lightest touch of a teenage crush—a clean listen, ideal for younger book lovers too.
