Perceptive and darkly funny poetry from the Forward-prize-winning poet.While Downriver contains the English urban pastoral and hymns to the Northern deities for which Sean O'Brien is justly celebrated, the poet has always been more a singer than even his many admirers have sometimes conceded: here, that lyric note is sounded more openly than ever before.With Downriver, his fifth collection, O'Brien has produced his most various and mature work yet. This is a poetry of both delicacy and gravity, assuagement as well as agitation, rivers that start in hell but later fall as rain - and will only strengthen his reputation as one of the most gifted English poets at work today.
