The Lord of The Rings. This book changed reading for me. I always enjoyed fantastical themes, but this one really got me. Then, I found out there was more. More background, more world building, more why.
I've never turned back. I re read it occasionally and I've read much of Tolkien's other works. Next on the list is to begin working through The History of Middle Earth. I will be starting this in the fall. It may take me quite some time to get through.
Links to tech news complaining about the tech. It's a sludge.
