L.A. Times: 2011 May 18
Soon after I became a school librarian, a teacher came to me about Mario, an eighth-grader who had never read an entire book. Mario struggled to read at all, and English was not his first language, but he was a bright kid whose teacher believed in him. I recommended a short, funny, mysterious book that appeals to reluctant boy readers. Mario took it home, read it in a week and came back with his friends in tow to check out the remaining titles in the series.
