As Stella and Sam explore the wonders of the natural world, they engage in creative and imaginative play that takes them to the ends of the world, the top of volcanoes and onto ice floes in Antarctica. Sam's ever-questioning nature continues to prompt Stella's whimsy and sense of adventure. She's keen to show her little brother all the magic and mystery of the universe without having to leave the backyard!

With wild red hair and an imagination to match, nine-year old Stella is truly a star in the eyes of her four-year-old brother Sam. He feels lucky to have a big sister like Stella, who does ninety-nine things a day and wouldn't dream of leaving Sam out of the fun!
