His best book and a deserving winner of the Forward Prize for Best Collection in 2006.
If you enjoyed the more high-profile 'The Wrecking Light', then you'll love this, which is written in a very similar vein, on similar subjects - a Ted Hughes-like approach to nature; relationships and family; characters from life - but pound-for-pound contains better poems: 'The Park Drunk', 'Swimming in the Woods', 'What the Horses See at Night', 'Donegal'... too many to mention.
It's also worth listening to Robertson read from his poems on the Poetry Archive to hear his granite-edged Scottish burr; it really brings the poems alive and gives a great sense of how to read his exclusively (?) free verse lines.
A brilliant book from a brilliant contemporary poet.
