The Novel

Embark on a thrilling international quest to unlock the mysteries of the universe.

Sean McQueen is a staid, middle-aged NYU literature professor leading an uneventful life, until he receives a cryptic letter from his intellectually and poetically gifted best friend, Dylan Byrne. Following years of extensive research, Dylan claims that he has discovered “the theory of everything”: a revelation that promises to alter man’s view of existence by reconciling science with spirituality. The two men arrange a meeting to discuss the paradigm-shifting theory, but after Dylan never shows, Sean discovers his friend has died under mysterious circumstances and the theory has gone missing.

Sean teams up with Dylan’s scientific collaborator, quantum cosmologist Emily Edens, to find the lost theory. Together they embark on the adventure of a lifetime—traveling from the busy streets of New York City to the mystical corners of Kathmandu where Dylan realized his groundbreaking theory. On their quest, they encounter extraordinary allies and fearsome adversaries, including a covert government operative code-named “Guru,” who is hell-bent on finding the theory first and preventing Sean and Emily from sharing it with the world.

The Lost Theory is an exhilarating adventure of self-discovery, full of magical realism, mystery, and romance, all wrapped up into a story overflowing with wit, intrigue, and a sense of ultimate redemption.

In the second book of the trilogy, The Devil’s Calling (coming in 2022), Sean is told, “it is best not to answer when the devil’s calling.” Sean does not follow the sage advice.
