This was actually a book I picked randomly from Amazon and is in a genre that I do not read all that often. It is a murder mystery. Actually, it is a mystery that turns into a murder mystery near the end of the story.
It is about a group of students attending a writing workshop at an extension school, and their instructor. One of the students is someone who has been trying to get published for a long time, without success, and is bitter as a result. This person is always pulling pranks on the members of the group, the instructor, and, as we find out later, various publishing houses. The pranks go from being just a little dangerous but causing no actual harm, to actually taking people's lives.
It is a situation where every single member of the group is a suspect. The story nudges the reader towards suspecting one person and then another and so on, until we find out who the prankster really was. It keeps you glued to its pages and keeps you guessing what's coming next. I managed to finish this book because it was a mystery but it was not spine-chilling scary. Probably because it built up gradually, starting with mostly harmless pranks. And I have to admit that I enjoyed it, though I do not usually like to read books in this genre. This is the kind of thing that would be fun to read again and look for the clues hidden in the story. Maybe I will.
