This book was in fact a short story, being the first audio book that I ever listened.
On this book, Tony Valdez is a “dispatcher”, a person that works by bringing people that were killed by other people back to live with 99% chance of success. There are more details on how this happens, but I’ll leave them to be discovered by whom decides to read/listen to the book.
Overall, a really interesting premise, which was explored on a short story that focuses on the solving of a mistery. This leaved me wanting for more, both by the author and the world created for the story.
