Here's a blurb:
International aid worker Frank Bowen's wife, Liz, goes missing in the wilds of Belize. The constables of San Ignacio find no trace. Years later, on a pilgrimage to Liz's remote 'grave,' Frank loses his way and his world. Exiled for witnessing a convergence of worlds, Frank becomes the ultimate 'doctor without borders,' tracking Liz's faint trail through the back roads of a parallel world at war.
