I think I've already completed this challenge? Not sure, I don't know where I have written my challenge, but I'm quite sure I've read books of the categories I intended to read - and that's good enough for me.
For example I've finally read the first of the Harry Potter series; which I would count as a book that was in my to-read list for way too long.
Twenty years ago I said I would read it when the hype died away, and I think this is a good moment to be true to my word
In the same spirit I have just started reading Lord of the Flies.
