I rarely ascribe my top rating of superb to a book of any kind. For me, a superb book has to score highly enough on every aspect that I rate books on to achieve 90% or more overall.
I’ve been rating books on Arukiyomi since December 2006. In that time, out of nearly 500 reviews, the following books are the only ones which I’ve rated as superb. I list them below in descending order of greatness with my fiction selection first and, below that, non-fiction.
