A book with something real hidden behind it - Kit Williams buried a golden hare and painted the directions into Masquerade; people are still digging for later ones.
Cover to cover, not the two you do on a train: a book of nonograms, sudoku, kakuro or logic grids, finished to the last page.
An escape room you can do at the kitchen table: riddles that unlock the next page, and an answer key you are not supposed to open. Journal 29 and the EXIT books are the usual way in.
The same idea drawn rather than written - panels connected by tubes and arrows that send you across the page or back three pages. Jason Shigaโs Meanwhile is the one everybody means.
One murder, a grid of suspects, weapons and locations, and just enough clues to eliminate everything but the answer. There are hundreds, in books and one a day online.
A book you play: numbered paragraphs, a choice at the end of each, a pencil for your inventory and dice if it has them. Start with The Warlock of Firetop Mountain, Lone Wolf or any Choose Your Own Adventure.
