This is still a really cool idea with the idea of an ancient death engineer, and the Pratchett-like juxtaposition of modern cultures, occupations, and financial concepts applied to a previously unremarked occupation in an ancient world is quite fun.
But, I happened to listen to these in the wrong order, and I suspect I liked this one less because of it. If this had been the first story I'd read about this guy and his occupation, then it would've been fresh and new, and then the 2nd one would've been fresh because of the introduction of the ghosts and whatnot as a fresh concept. But in the reverse order, this one seemed like it didn't offer anything different enough from Ghost in the Death Trap.
But that's not really the author's or Escape Pod's fault, just my own for listening to them in the wrong order.
