If a book is almost never abandoned, that might only indicate that it is short, or really easy, neither of which are hard to tell from a few seconds inspection. This tells you something you might not otherwise know from a few seconds' inspection.
I imagine the least abandoned would be something that comes late in a series (or at least from an author with many similar books), where basically everyone who picks it up already knows that they will like it (those who don't were filtered out by the earlier books).
