Heaven's Thieves is a collection engaged with the big questions -- What are bodies for? What does it mean to be alive? What is beauty and why does it have such power over us? What is the point of art? -- and the urgent ones -- how to live in a shattered ecology, what to do about grief, illness, betrayal. Sinclair turns her attention to these questions with fearless curiosity, economy, and an originality born of her willingness to pursue her own line of inquiry to its limit. These poems get close and cut deep, mixing subject and object, surface and soul: "Red mud glistens / like cut fruit -- or like the knife / that did the cutting, laid down." In this, her fifth collection, Sinclair knows that nature is both "done to death" and "inexhaustible;" that art is an elegy for experience. Experience and its value are changed in these poems. They are as wise as they are disruptive, and they change us as surely as they remake the world.
