We love a good "weepie" in our house and I am fascinated by the special skill and craft required to reduce a child to tears with words alone - especially as they start to become slightly more cynical and "knowing". I can offer three books that have produced tears in our house - the brilliantly understated Bridge to Terebithia" by Katherine Paterson (made into a truly horrendous film), Morris gleitzman's "then" trilogy, and a surprise contender from my (then) 10 year old "is anybody there ?" by jostein gardner. Notably failures have been Michael morpurgo - private peaceful (verdict- (too many bad things happen - just too silly), boy in striped pyjamas (surprise failure- probably because too widely read by peers to be cool) and philippa pearce "a dog so small.". My girls are 14 and 11. Any more suggestions?
