You know the one! I had a free copy on my phone, thanks to Google Books. This is the first in a new series, books I read entirely on my phone, which is something I am doing lately in order to avoid browsing Twitter too much (after Wordle, and Korean vocabulary of course). This book is pretty good, as you already know. I've seen multiple movies/TV series about it, so I also had a pretty good understanding of what was going to happen.
