FlagImani Elizabeth Jackson '"We are and were a Black family," Jackson writes and the dead matter of history hums. In this book of nearly subterranean intensity, I feel the poet hum, and it erodes borders between the poet's mouth and the river's, between forms of matter and states of consciousness. I feel Black life too, in its impossible thickness, and all of this in a beautiful economy of language that seizes without coercion and shapes without chisel.
