Embark on a Thrilling International Quest to Unlock the Mysteries of the Universe

AUSTIN, TX / AGILITYPR.NEWS / September 21, 2021 / New novel weaves adventure, suspense, quantum physics, and spirituality, in the search for the lost theory of everything


Michael Kelley’s remarkable debut novel is a captivating odyssey with simmering romance. In The Lost Theory (Greenleaf Book Group, Sep 21, 2021), Kelley introduces protagonist Sean McQueen, 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.


The Lost Theory by Michael Kelley is a compelling thriller with a strong plot, a story that will appeal to readers who enjoy the puzzling kind of plotting they find in Dan Brown’s work,” said a reviewer from Readers’ Favorite. “The originality in the voice and style, as well as the author’s ingenuity in plotting complex scenes, make the story a spellbinding read.”


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.


“I confess that I’ve never read The DaVinci Code, but if it’s half as fast-paced, outright entertaining, and mind-blowing as The Lost Theory, I’d be tempted to give it a try,” said Larry Dark, Director of The Story Prize. “Michael Kelley has hit a home run on his first swing.”
