Anne and Jack return to the tree house. This time the kids find themselves in the time of King Arthur. they meet lords and ladies, knights and knaves. They learn the hard way that you can’t just walk into a medieval castle and poke around.
I like the sibling bickering between Jack and Anne. It reminded me of me and my brother when we were kids. I highly recommend these books to early chapter reading kids.
