For many summers Veronica King has visited her Grandparents enchanted farm with her cousin Clay. But this time the summer would be lost into a mystical journey within Grandma's forbidden artwork of creative worlds. Their only way out is to "remember" and solve the mysteries of what Grandma said. Even that may not be enough.
