Love in a Life, Andrew Motion''s sixth volume of poetry, marks a conspicuous development in the work of the founder of the modern Narrative School. Directness and a new colloquialism are wedded to Motion''s distinctive obliquities in a volume where the idea of marriage governs the architecture of each poem and the book as a whole. The stories of two marriages gradually emerge, like chapters in a narrative, and are themselves bound to more public material, so that each lends profound resonances to the other.
