As a kid, my library handed out tokens for every chapter kids read as part of a summer reading program. At the end of the season, those tokens turned into currency for spending at a karaoke BBQ, with games and toys up for grabs. I'll never get over the trauma of singing American Pie (I had not realized just how painfully long that song really is), but I will always foster the same love for mass consumption of oversized chapter books. Fast-forward a few decades, and my reading rewards look a little different. No tokens, no karaoke mic, just me, my Kindle, and Libby, the app that lets me hoard library books without a single overdue fine.
