It's one of these and I ended up ranting at DS about how if his school ever sent him on a trip like this one both his dad and I would be complaining... Basically the premise of the book is that the class are going to the library to hear a talk by two authors. One writes books about spies, the other writes books about fairies. Only the spy author can't come. Cue pages and fucking pages of how awful it is for boys to have to hear about silly fairies...
