The Maze of Games by Mike Selinker and Pete Venters
The Maze of Games is a full-length hardback puzzle novel by puzzlemaker and game designer Mike Selinker, with beautiful illustrations by Pete Venters. Its 192 pages contain a multitude of puzzles interwoven with a deeply engaging story, all woven together in a "solve your own adventure" style which will keep you jumping from page to page.
The main characters are teenagers Colleen and Samuel Quaice, two teenagers living in England in the year 1897. During a visit to the Upper Wolverhampton Library, they discover a musty book called The Maze of Games.
