I received a free review copy of the Anonymous Source (Audible Edition) in exchange for an honest review, but I also owned the Kindle version. I read along as I listened. First of all, the narration is among the best I have heard. All of the characters literally had their own voices, and through the power of audio editing, the narrator made them all sound genuine and unique. Combine the excellent story-telling of AC Fuller and the superb narration of Jeff Hays and you have hours of entertainment that will keep you coming back for more. I did figure out who the anonymous source was fairly early, but that didn’t take away from my enjoyment of the story. I’m also pleased to find out that there is a sequel coming soon. I can’t wait to read/listen to it.
