The Silver Key has the power to send whoever uses it to a world where all their wishes have come true... if they're lucky. Many have used it, and now it's Penny's turn. However, she soon finds out that some doors should've stayed closed. The Key leaves her stranded in a dystopian future where the King in Yellow has taken over the world and baby-eating lizard people roam the streets. Now, Penny must find her way home, or be stuck there forever. Note : Penny and the Silver Key is also available in 2 volumes, Penny and the Silver Key Part 1 and Part 2. Warning : this book contains violence, swearing, and a little bit of naughtiness, and therefore is NOT appropriate for children.
