The Arrival by Shaun Tan
I love this book! I knew immediately it was beyond First Son (and perhaps even a little upsetting for him), but I think it has enormous potential for middle school and up, even into college. It's a graphic novel, a rendition without words of an immigrant's journey to a new country (not ours) and his struggles to make it his home. I've read through it a few times and always find something else to amaze me. I highly recommend it!
