The Dreaded Waiting

I love to read.  It was my escape as a child, and my vacation as an adult and I honestly don't know what I'd do if I couldn't get away every now and then to catch up on my favorite stories or revisit an old one.  Recently, one of my favorite series was updated with a new volume.  I knew that I had been waiting for a while for this book to come out but I didn't quite realize just how long until I began to read reviews for it.

Four years.  Four years since the last book.  Upon realizing this, I began to wonder just what exactly is the limit for a reader before one decides it's too long.
