The Seventh Reality. The Dan Provocations, #7

Welcome to the Inn of the Sixth Dan-where time stands still, the drinks never age, and neither do the guests. It's the perfect stopover for the galaxy's richest drifters. especially those chasing enlightenment at a place no one can find, known only as Satori. Tom Two-Dan $mith (sic) runs a lucrative business sending these pilgrims on their way. There's just one problem: none of them ever come back.
When a powerful oligarch demands answers about his missing son, the job falls to Barry Saint-Albans-officially the second-greatest detective in all known universes. His investigation leads him across bizarre frontier worlds, corrupt tax havens, philosophical dead ends, and civilizations that probably shouldn't exist. But the deeper he goes, the clearer it becomes:the path to enlightenment might actually be a trap.
And with a heavily armed starship threatening to wipe the Inn from existence, Barry is running out of time to solve a mystery where the final answer may be worse than the question. If enlightenment is the destination. why does nobody survive the journey?
