Shaun Tan, Rules of Summer (2013)
I highly recomend the whole book. It's full of stunning art and tells a compelling story of a Kid, who moves to a different country (in Tan's case it was Australia), where everything is new, fascinating and deadly. It's also a story of an older local kid, who becomes an unwilling guide to the new kid, gets fed up with explaining everything and being a babysitter and has to find compassion to create a brotherly relationship with the new kid. It's truly some amazing storytelling done solely by means of oil painting.
