A marine biologist, peaceful and focused, is documenting coral reefs alone underwater. His routine gets interrupted when a super curious cecaelia king saves him, then disappears. Days later, Elias finds a gift on his rock: coral. He leaves one back: a notebook. What starts as "thank you" turns into daily notes, secret meetings, and a love neither of them expected. But in Kael’s world, loving a human is treason. Now Elias must choose: stay safe on the surface, or dive deeper for the king who said "I’d choose you again" — even if it costs them both everything. Some conversations don’t need words. Some risks are worth it.

He was sent to kill him. He was also sent to kill him. Azrael, Prince of Hell, and Aurelius, Seraphim of Heaven, were supposed to be enemies. But when they spare each other’s lives, they become the most wanted beings in existence. Hunted by angels and demons, bound by a prophecy of “Light and Shadow,” they discover the Heart of Convergence — and the only way to save the world is to sacrifice everything. In a war between Paradise and Hell, their forbidden love might be the only thing powerful enough to create a new world. One choice. Two souls. A love forbidden by Heaven and Hell.
