Query: A brilliant fusion of theme and form

This is perhaps the most gripping book of poetry you'll ever read. It's a great place for someone who thinks they don't like poetry to start reading, because it has the pacing and tension of a thriller; it'll make a believer out of the most reluctant of readers. But for people who already love poetry, it offers even more reward: an incredible fusion of the form with the theme. Mose undergoes such severe tests and agonies; everywhere those emotions are echoed in line-breaks, fractured sentences, and a growing sense of loss and Mose's shattering mental state. The structure is incredible; the poems are numbered in the days that remain of Mose's jail sentence, so they grow smaller even as time continues forward, meanwhile in Mose's mind, we move ever backwards towards the crisis that put him where he is. It makes time seem to collapse. This book is astonishing.
