The poems in Catherine Pierce’s new Danger Days celebrate our planet while also bearing witness to its collapse. In poems steeped deep in the 21st century, Pierce weaves superblooms and Legos, gun violence and ghosts, glaciers and contaminant masks, urging us to look closely at both the horror and beauty of our world. As Pierce writes in “Planet,” “I’m trying to see this place even as I’m walking through it.”
