Ask HN: Where do you find quality book summaries and lists?

There are a few blogs, like Derek Sivers' (https://sive.rs/book) as well as Graham Mann (http://www.paulgraham.com/books.html) that have what I find are thorough book summaries that capture the book contents well. Additionally, I find the set of books they review to have a high signal to noise ratio. Are there similar sites you have to share?
