Why is this book suggested to me?

[JC]

I have already marked a duplicate of this book as read on my list of books. There shouldn't be multiple entries for the same book. I get recommendations to read this book, but I've already read it - this is just silly.

I could mark it as 'Not interested', but this would be inaccurate and might spoil the recommendation algorithm.

This is actually a 'study guide' for the George R.R. Martin title, so the algorithm thinks you will be interested in it.

Aww, ok, I didn't notice this when I first checked it. Super, thanks!
