Connie is not a child who likes books. So she's not too pleased when she's sent to stay with her eccentric author aunt. But then Connie meets Ruby - a book fairy - in the dusty old library. Ruby is in trouble: she has broken fairy law by trying to take something - a piece of jewellery - back to fairyland through the 'gateway' of a fairy-dust-sprinkled book. And now the jewellery has disappeared and Ruby can't get back home!

Can Connie help Ruby find the missing jewellery before the doorway to fairyland is closed forever?
