Just finished Canned by British author Alex Shearer. Heard a great book talk from a school librarian friend. She took some cans without labels to the students and told them about Fergal, the main character in this book, who was obsessed with collecting cans without labels. He loved the mystery of it all. His parents say, "Enough is enough!" and order him to stop collecting. He must dispose of a can if he gets a new one. As he opens one before he disposes of it, he finds something that is not a food item. The adventure and suspense begins. A little gruesome at times, but I think middle readers will love it!
