I'll also be counting short stories, but just to follow the rules as closely as possible I'll consider 2 short stories to be one book.
I'm going to be using Fastolfe's rating system.

= the book is a turd, avoid at all costs

= not sure what to make of it

= okay book

= good book, recommended

= great book, highly recommended

= reading in progress
