If you’ve played Riven and enjoyed it, I encourage you to check this one out. It’s well worth the read.
And for any Myst geeks out there, the book cover is true to the game. There are five different covers, and since I got it out of the library there was no way of knowing which one it’d be. The one I got has Gehn’s 233rd Age on the cover. I wanted the Tay cover. Bother. If you get the book because of me, leave a comment and let me know which cover it is!
