This text is constructed as a dialogue between an adult (dismayed at the grammatical mistakes written by his offspring in his holiday book) and a child (more interested in video games than reading). The adult so she has to make the child understand the need and usefulness of grammar. Would follow eight days of intensive courses - but fun - which will each have a theme: Why grammar distinguishes us from the chimpanzee! How comics preceded the alphabet; Words are people like you and me; The names also have a family life; Like the planets, the names have satellites; We must look after our verbs such as motors; The syntax is eternal; Reading my brother worry. The idea is fun and I really enjoyed the first five chapters (the section devoted to Latin, supposedly dead language but in fact particularly vivid, I liked). For cons, I found that the pace is accelerating sharply in the sixth chapter, is racing in the seventh chapter, to slow down the eighth and final chapter. The pace of the book is a little uneven for my taste: it is a shame especially when considering the dense grammatical content of chapters six and seven ... Fully enjoy this book already assumes a number of grammatical knowledge: therefore I do not advise beginners ... but I do not advise to grammar fans either!
