I really enjoyed this book. It's technically a sci-fi because it's set in the future, but the story is more mystery/police operational and it's a really easy, lightly-humorous listen. There are two of the same title by different narrators, Wil Wheaton or Amber Benson. It looks as though the Amber Benson one is the only one on offer, but it might be both and just not showing for me because I already have the Wil Wheaton version. If you do have a choice go for the Wheaton version as he is one of my favourite narrators, really lovely voice and excellent expression of nuance without over acting.
