After doing a re-read of Wonder, I felt compelled to look a little further. I watched some clips from the movie (which I had seen at some point), I checked out some author interviews and Q&As. I found it a little funny that she insisted there wouldn't be a sequel ... yet then there were some "companion" bitty books that arrived on scene. I was glad I was able to find a compilation of the three short stories: The Julian Chapter, Pluto, and Shingaling. The first features a closer look at Julian, who played a major role in Wonder (and then has it's own companion piece, a graphic novel about Julian's grandmother ... I also checked this out of the library). Pluto is Auggie's childhood friend Christopher's perspective (just mentioned in Wonder, but didn't really play much of a part), and then Charlotte's POV. 

All were told in first person, very conversational tone. While not directly addressing the reader, it was as though these characters were just telling their story. Julian's covered quite a bit we already knew, from Wonder, but gave more background, and then continued to address the time after Julian had exited the scene in the first book. Christopher shared some past history, and then a "present" timeline, a day in his life. Charlotte's covered some of what we already knew, but veered much more into the girl drama that had little to do with Auggie at all. 

I really enjoyed these add on stories - I don't know if these could really be appreciated without having a relationship with the original Wonder book, and they aren't necessary, but a nice addition. Just a little more insight into the Wonder world and some of the characters that didn't get the spotlight in the first book. Anyone who was a fan of Wonder would like these too I think.
