Sending Secret Codes

In Mr. C's fourth-grade class, Arius, Londyn, and Averie sat at their desks, listening to the rain tap against the window. As they glanced around the room, their eyes fell upon a dusty, forgotten book in the corner. Curiosity sparked in their hearts, and they tiptoed over to investigate. The book's pages were filled with strange symbols and mysterious drawings, and the friends couldn't resist delving into its secrets. Little did they know, this book held the key to a magical adventure.
