It's December! And that means advent calendars are all the rage for the next few weeks, and I have one for you to check out! This advent calendar will open a new door every day, so be sure to bookmark the website and come back to check it each day. Books are only guaranteed to be free on the day they’re revealed. Some may be free for longer, but I recommend checking the calendar every day so you don’t miss any books.
If you're wondering… yes, I have FIRST FLYGHT in this calendar. Can you guess which day?
