As Carla knocked, Pita peered in through the glass. The interior of the shop was dark, but she could see that it was filled with untidy stacks of hardcopy texts bound in boxy coverings. These were books—the old-fashioned, difficult-to-use data storage units that had been so popular in the last century. Pita couldn’t see the attraction of them, and wondered how a place like this could make any money. She’d take a Pocketpad graphic novel over one of these dusty antiques any day.
