Actually, the author worked closely with Bethesda and The Imperial Library/Michael Kirkbride to write it as explained in the "Foreward". Bethesda even told him certain plot points and events to add in to tie Oblivion to Skyrim. I.e, the Thalmor are in the book, even though it came out 3-4 years before Skyrim. As is the writ of Monument, the Red Year, the Argonian invasion of Morrowind... all the things you guys found out in Skyrim, I knew before the game came out because I read the book. It's canon, trust me.
