When is it and how often does it come around?

You collect books and give them to reading drive, then buy prizes in the shop based on how many books you turned in during the drive.

There is no set time for the reading drive. It happens whenever staff decide, but can go 2 or more years between drives.

Thank you for the info! I was just confused because I remember participating in it once and then it never happened again lol Thanks again! :)
