Mark of Cthulhu: An Escape Room Adventure, by Gauthier Wendling

An escape room adventure book based on one of H.P. Lovecraft's most feared creations—Cthulhu. Are you ready to dive into the ruthless world of Lovecraft? You will meet the worst creature the world has ever known: Cthulhu, the ancient god who dwells in the seabed. The latter has been awakened and is determined to trigger the end of the world. With his relentless logic, analytical mind, and sense of observation, there is no doubt you will have to be better than the old God to hope to escape his mystical traps. Inspired by real-life escape rooms, to escape, you must explore the different rooms, look for clues, solve puzzles to unlock certain situations, and hope to get out alive! Use the notebook to collect your clues. Take care, because there is only one way out, so you'll have to be smarter than the one who locked you in!
