I took a hiatus too - I think it was those 2 late in life babies I had. I didn't mean to stop reading, I just couldn't stay awake and read anymore. I stopped somewhere around From a Buick 8 and jumped back on at Lisey's Story.I started reading when I was around 24 or 25 I believe, so, it would be 26 or 27 years.
Although, I stopped reading SK when I was around 38 and didn't start reading until this year so I had a 13 year hiatus.
