A mysterious child with uncanny abilities. A deadly threat to dominant religions. A prey to merciless secret organizations. An unimaginable origin that unfolds within the bowels of hell.

Theon E. Rex is no ordinary boy. Discovered as an infant in a symbol-riddled well near Manor Clos Lucé, Leonardo Da Vinci’s former residence, he soon manifests extraordinary powers ranging from the stunning to the devastating, attracting the attention of the Vatican and other powerful organizations bent on exploiting or destroying him. Terrified the secret behind his mysterious origins will reduce biblical doctrine to ashes and crush his empire, the Pope himself orders his death.

Even Satan has designs on Theon. Hell’s fury descends upon him as the Dragon Lord whisks the boy prodigy to his infernal realm, determined to weaponize him and bring destruction and desolation to the Kingdom of Heaven... and to Earth. Of all the echoes - restored human souls - roaming heaven and hell, Leonardo Da Vinci comes to Theon’s aid, helped by Satan’s crossbred daughter and other unlikely allies.

A frantic race ensues across hell and into heaven in hopes of finding a cure to Theon’s explosive curse. But a misguided God swears the boy will not cross heaven's borders. What they discover about his origins, no one - neither Da Vinci nor even God himself - could have imagined.
