I’m in the middle of changing the rating system to add half-stars (i.e. 3.5/5.0). This will give me a little more granularity in rating the books I read most.
Some of the buckets are going to look a little odd until I get everything settled. (For example, as I type this there are a whole 3 books that have 4 stars.)
But the ranking of books (which series I recommend more than which other series) hasn’t been changed. So if you’re looking for something good, start at the top and work your way down.
