The book about a cactus named Ai is a light, heartwarming story about a prickly yet very cheerful flower. Together with your child, you'll stroll the streets of the old town, smell the aroma of cocoa, explore the abundance of fish in Joe's shop, and, of course, experience the main character's life changing experience. You'll listen to classical music, discovering the sounds of a cool morning, the music of a sun-drenched, nectar-filled spring, a threatening storm, and a melody reflecting the cactus's emotional decline, loneliness, and anxiety. Despite difficult circumstances, Ai teaches us to stay positive and to encourage ourselves, and at the end of the story, she reinforces this with the book's main message: all bad things come to an end, good triumphs over evil, and after adversity, there will surely be joy.
