In her astounding third collection, Nikki Wallschlaeger turns to water—the natural element of grief—to trace history's interconnected movements through family, memory, and day-to-day survival. Waterbaby is a book about Blackness, language, and motherhood in America; about the ancestral joys and sharp pains that travel together through the nervous system's crowded riverways; about the holy sanctuary of the bathtub for a spirit that's pushed beyond exhaustion. Waterbaby sings the blues in every key, as Wallschlaeger uses her vibrant lexicon and varied rhythms to condense and expand emotion, hurry and slow meaning, communicating the profound simultaneity of righteous dissatisfaction with an unjust world, and radical love for what's possible.
