Gleff, you must be an Aman Junkie.
Option number 3 sounds about right.
I recall my husband having to return the book he was reading to one of the Aman libraries before he had finished it (because we were checking out). Knowing that he had a birthday coming up, I decided to contact the hotel to find out the title. I asked them to check their records, telling them that he was reading something war or battle related. It turns out, they did not have a sign-out record, so they emailed me digital photos of their war and battle book covers so that I could identify the book by sight and purchase it through Amazon!
