I say plenty but never with sound;
Free to say anything, yet always bound.I like to be kindled but never kindling.
I'm always turned yet the same way round.Born from a tree, but not in the ground,
Small, yet inside whole worlds are found.
It's the first time I've written a riddle. I worry that it's too easy, but then riddles are much more obvious if you know the answer. Really I've no idea of how easy or hard it is, but hopefully it gives a few moments of entertainment nevertheless.
