Every month, Elza and I pick a theme around which to plan our posts. For May, we went with Lock & Key.

And because I enjoy little challenges, we created a list that embraces the theme in more specific ways. We definitely have fun trying to apply the theme to middle grade books. Piano keys. Locks of hair. Safes & thieves. I share my book finds on Twitter, but I’ll be doing a sort of summary post here, too.

You’re welcome to play along. Just use the #MGCarousel tag when you tweet.
