I appreciate this book because it's the foundation for Little Pilgrim's Progress which is a favorite of mine since childhood. I did find the old English of the adult version difficult to follow in places and often had to reread a paragraph to fully understand what was being said. 

I found it interesting that the religious turmoil of the age in which this book was written were very evident in the story.
I couldn't quite figure out whether this book was meant to be an allegory, or a story. It fell oddly in the middle in a way that was a bit jarring.

Over all, I still love the story and it was interesting seeing a more mature version of a childhood favorite. It was definitely worth reading, but I can say honestly that Little Pilgrim's Progress is my clear preference when I decide to reread this story again.
