This is really a very great app mixing two of my favourites- literature and jigsaw puzzles. I know the app is very new and the developers are working very hard on it. Still I have given it 4 stars because only one or two novels of the entire collection have more than 3 chapters. There are people like me who like to move over a new book only when they have finished the previous one. So it's slightly disappointing to see only 2-3 chapters in most of the books I click to play.
