I like the themes
back to school and
courtly behaviour and
the truth is out there
those are all themes I could find suggestions for, and would be fun to see what others come up with - the themes could go any which way for suggestions
and voting results will be interesting to see too. I could see almost any theme fitting both fact and fiction as well - how fun!
All the while I would hope the art-one wouldn't be too not-my-style...
...that being said, I am already pleasantly surprised with our first book, I would never have come across the Passing were it not for the New Leaf book club and the colours-theme.
Edited to add (almost forgot the main point of my post!):
My suggestion for a theme is
spring forward... I'm thinking of the memory rule for Daylight Savings Time (northern hemisphere only?) and the season Spring, and the physical item...
