From the back: As the iron bars close round Creggan, the captured golden eagle, his heart begins to die. But inside the cages is Minch, a female eagle, who is determined to teach Creggan not to forget about freedom. And outside is Mr Wolski, the Zool's sweeper, a man haunted by the horror of captivity - his own and the birds'.

When the time comes Creggan and Mr Wolski are ready for the final struggle towards Callanish.

Brilliantly imagined, spare and tensely plotted, Callanish is dedicated to Goldie, the eagle who escaped briefly from a London zoo in 1965.
