I was fighting my way through a dank castle to save a lovely princess when my wizard informed me that Amazon.com had Robert Silverberg's
Gilgamesh the King for $1.99. Having no cell service in this magical land and not wanting to miss out, I fled for the magic portal and returned home. If the princess can't be bothered to save herself, she doesn't deserve saving. I'll just retire to my easy chair and turn on my Kindle.
