Audible does this thing where when I search for an author, it constructs a bag of words based on the titles of books that show up for that author, then retrieve based on that bag of words, then rank by like popularity of the returned books. So if a different, more popular author has written books with similar titles (which is very easy given a trilogy with storm-themed titles) you will occasionally see a book by the wrong author as the number one result.

Every time it happens I want to quit my job and force them to hire me to fix it.
