I don't know why I hesitated so long to get this novella. It certainly is a departure to JL's usual, and I don't know how authentic his research is (though I know he does massive amounts of research and he sought clarification/correction from his Japanese readers before releasing) but I enjoyed all the detail in this book. Josh has a way of writing exposition so naturally, you don't realize you're learning things, lol. There were some questionable "police procedure" which usually makes me impatient with characters who act unprofessional while on the job. Overall though, really enjoyed this one.
