The Tangle Box is the fourth book in the Magic Kingdom of Landover series.

The Tangle Box, by Terry Brooks
I think that this one is my favorite in the series so far. Ben ends up getting trapped in the Tangle Box with Nightshade and Strabo. None of them know who or what exactly they are, and they definitely don’t remember being enemies. They don’t completely get along, but without their “labels,” they actually get along a lot better. The three have to work together to get out of the Tangle Box.
Terry Brooks never fails to write a great adventure. Nightshade is now one of my favorite characters, because of the different side of her I got to see in this one.
The next book in the series is Witches’ Brew, which I’m assuming means I’m going to get more of Nightshade!
Note: Read this one in July, too. I swear I will get better at this!
