Book Coming Soon

Discover the historical journey

A set of magical postcards sends two strangers on a collision course with the past.

Guided by a lost historian’s correspondence, they must survive the vibrant and dangerous courts of the ancient Middle East to unearth a secret hidden for millennia, before a shadowy power unravels history itself.

From My Wall to the 'Postalized Plane.'

My journals are filled with the fingerprints of countless journeys, over 250 postcards, 190 banknotes, and dozens of maps that each represent a moment of human connection.

They are anchors to real people and forgotten places, tangible proof our stories are what bind us across borders and generations. 

That simple, powerful idea is at the heart of my novel: that a single message, sent with purpose, can bridge any distance, even time itself.

From the markets of Egypt and Nepal to the alleys of Ethiopia, these 190+ banknotes represent the heartbeat of 60+ nations and dozens of hostels.

They are the physical currency of the Postalized Plane, tangible evidence of worlds that are constantly folding and unfolding

Something you will read in the book.
