Amazon has a bunch of "originals" ... short stories around a central theme. They are included in KindleUnlimited (which I have presently) and I think also included (text and audio) for Prime subscribers. The stories/collections can be hit and miss, but can be a good "palate cleanser" between books. So short (just over an hour listening time to the audio) it's not one many would BUY outright, but are perfect as little inclusions in paid subscriptions (like KU/Prime). 

Nonfiction, told 1st person, past tense ... a writer for the associated press (I don't see him as an "author" of other "books") has this expanded "article" where he plays a part. Some other reviewers mention hearing about the 'missing dog' in Vermont and the city-wide search over a couple years... maybe it was based on locality, or I just don't really watch much news. I wasn't familiar with the details at all, so the story here unfolded fresh for me. 

It was interesting - glad that there was a happy ending.
