Based on the multi-award winning novel by David Almond.

When a move to a new house coincides with his baby sister's illness, Michael's world suddenly seems lonely and uncertain. Then, one afternoon, he stumbles into the old ramshackle garage at the end of the garden, and finds something that will change his world forever.

Skellig is a strange and extraordinary creature, as ancient as the earth and now mired in a life of nothing and nobody. With the help of his new friend Mina, who teaches him to look at the world through different eyes, Michael nourishes the reluctant Skellig back to health. As his baby sister grows ever more frail in hospital and his parents fade away with her, Michael needs a miracle to hold the family together. When he realises that Skellig may have much more power than he would ever admit to, Michael knows he has to give Skellig back faith in his own power to heal, before it is too late.
