An epic tale of good and evil based on the four horsemen of the Apocalypse found in the book of Revelation.

Using the four horsemen of the Apocalypse to symbolise the four Gospels, four transcendentals, and four forces of the universe (air, water, earth, and fire), Sweet and Wagner weave a fast-paced, end-times tale of good vs. evil and the promise of a new dawn for humanity.

Set in 2048, when planet Earth is suffering from the damaging effects of years of misuse and abuse, cultural history professor Paul Binder receives a mysterious letter that leads him to examine a lost 2nd-century Diatessaron manuscript.

Ancient prophecies, cryptic letters, and strange events set him on a course to uncover the missing clues that could lead humanity into a new age. Each character embodies elements of the four horsemen in a race to save the world from total destruction. Layered with forgotten symbolism from the ancient, Jewish, and Christian traditions, the novel is a type of engaged fiction in which the main character's lost journal serves as a guide to the reader in interpreting clues and understanding the novel's conclusion.
