Skellig

By David Almond

Michael moves into a new house, and finds a man who has no name. He ventures into this new mysterious world and finally confides about the mystery man to his friend Mina. They try to find a cure for this strange man's arthritis but he is unwilling to cooperate.

As they slowly grow closer, the mystery man gets more active and able.

On the other hand, Michael's premature sister is on the verge of dying.

Will they all pull through?
