At the ends of the earth is Skellig Lir, a dreamy magical island that is inhabited by mysterious people with strange powers. To get there, Lily Quench and Queen Dragon must brave magic, storms and seas swarming with deadly sea dragons - and Ariane, the rebellious keeper of the lonely lighthouse of Skellig Mor.
In the depths of an undersea cavern, Lily struggles to communicate with the sea dragons and escape the skeleton-filled tunnels beneath the lighthouse. Only then can she return to Skellig Lir and answer the question that will complete her quest: to enter a fantastical library that has existed from the beginning of the world.
