"Wonder", by R.J. Palacio, is a wonderful story about a ten year old boy with a facial abnormality who goes to a traditional school for the first time as a fifth grader, and the book is divided into 8 sections, each section told in first person by a different character of the story. It was not too difficult to follow throughout the pages, remembering which voice I was reading. (Although I had to really force myself to read the section in all lower case with no punctuation except periods.) I get that this book was (apparently) written for children, but because the author switched perspectives so often, I don't think it would be a stretch to ask to have a peek into one of the adults' minds.
However!
