i can spend lots of hours in a bookstore looking through books after books that might catch my interest...in my experience its best to go alone if the bookstore is part of my itinerary of the day...most of my companions when i go to the malls don't have the patience to wait around for me...my hubby once told me next time to go on my own when he was forced to sit outside and wait for me to come out that he had to come back inside again and reminded me that i'm out with him....hehehehe.
also if there are movie adaptations of the book or if it came highly recommended by another reader or author's that i like.
