Jane, Mark, Katherine, and Martha are having a boring summer until one day, Jane finds a coin on the sidewalk. When she inadvertently wishes for a fire, she discovers the coin's secret: it grants wishes! But you have to wish two times your wish, otherwise, it will only grant half of it. Soon, they use the magical charm to go on adventures, including meeting Sir Lancelot and going to a desert! What will happen next? How will the coin change their lives? This book was great, and I liked how the author told the story. Also, it was super funny! I recommend this book to people who like hilarious books with a bit of fantasy.
