The IMPAC judges said:
We admire the novel's beauty and clarity of language, its formal restraint which gives it subtle power, its commitment to its terrible subject, its passionate evocation of the human soul and the will to survive.
The Independent called it, "One of the greatest prison novels of our age" and the Irish Times called it, "One of the most beautiful, humbling and important books most of us are ever likely to read." So, well thought of then! I best get on to it.
