Very sweet story about two Mongolian boys who transfer to a Liverpool school. They meet a young girl named Julie who they appoint as their "good guide". She helps them learn all about local culture, sports, etc. However, Chingis and Nergui approach things very differently and culture clash inevitably ensues. The way they see the world is so different from how Julie and her classmates sees it. Through photographs, observations and events, she discovers what's really going on with this family.
It's a very charming book and I highly recommend it. I love how the mystery unfolds with polaroids that reveal things as you go along.
