'It is the long school holidays and Sarah is lonely and bored. When visiting her great gran, she is drawn to a girl in a picture hanging on her wall that she’s never noticed before. To her surprise, the girl steps right out of the picture frame. Emily is everything Sarah isn’t - strong minded, adventurous, and wilful. Soon, Sarah cannot imagine life without her new friend, even though she creates tricky situations at the drop of a hat. And then...well, you’ll have to read the story to find out what happens!'
