Eyewear's British Poetry Book of 2011

There are many contenders for the British poetry book of 2011 - certainly, Roddy Lumsden's Terrific Melancholy is a runner-up - however, the collection I keep returning to, in my mind, is Clare Pollard's Changeling, from Bloodaxe.  The poems are startling, formally inventive, the diction never less than astonishingly varied - it is a passionate, angry, moving, alarming, splendid book.  Reading it inspired me to think of new things poetry could say and do; in this collection Pollard moves into the front rank of British poets.
