In the fabled, magical library of Skellig Lir, Lily Quench hopes to discover a way of closing all Eyestones - magic stones that her enemies plan to use to travel through time and invade Lily's home! On the quest to find the library, Queen Dragon gets trapped on the island of Skellig Mor. But when Lily tries to rescue her friend she is pushed down a cave on the island by Ariane, the devious lighthouse keeper. Ariane disguises herself as Lily and flies off the island on an oblivious Queen Dragon. It is now up to Lily to escape from Skellig Mor and find the answer to the mystery of the eyestones with only the aid of her wits, night-glasses and a magic flying cape?
