Skellig by David Almond

AZ: "When a move to a new house coincides with his baby sister's illness, Michael's world seems suddenly lonely and uncertain. Then, one Sunday afternoon, he stumbles into the old, ramshackle garage of his new home, and finds something magical. A strange creature - part owl, part angel, a being who needs Michael's help if he is to survive. With his new friend Mina, Michael nourishes Skellig back to health, while his baby sister languishes in the hospital. But Skellig is far more than he at first appears, and as he helps Michael breathe life into his tiny sister, Michael's world changes for ever . . ."

Skellig is a creature trying not to be an angel. A baby clinging to lfe that you want to live as badly as the young boy narrator does. A reminder that although many times I wish I was 'ordinary' I don't have to be:

"They say that shoulder blades are where your wings were, when you were an angel ... They say
that they're where you wings will grow again one day"

"Sometimes I think she's never quite left Heaven and never quite made it all the way here to Earth."
