@TheAromaofBooks created a sort of choose-your-own adventure except with reading prompts. Below is a link to a spreadsheet where each cell is a step in the maze.
All the cells are blacked out so you must un-highlight to see the other prompts (you have to save a copy in order to use the maze). You can leave it that way, or un-highlight the entire thing. You can use one book per square or go as far as you can with that book. However works for you!
