Brent Armendinger's poems are smart, elegiac, and wonderful, filled with formal play, the vapor between rainfall, skies full of knives, and the memories of breath. Undetectable celebrates and makes visible the bodys perforations, the openings between the body and the world, and manifests them in the fracture evident everywhere in this book. These poems pose questions of loveliness and loneliness: Where do syllables take us? and What would it take for the window / to be the wish?
