Reddit reviews RuneScape: Legacy of Blood

There's a book about RuneScape you can read: https://www.amazon.com/RuneScape-Betrayal-T-S-Church/dp/1848567227

Someone also made a PDF of RuneScape history. It has over 400 pages. Very interesting read.

EDIT: There are 3 books you can read. They are all on Amazon. I believe they are also canon.
