Martin Espada is a poet who stirs in us an undeniable social consciousness, says Richard Blanco. Floaters offers exuberant odes and defiant elegies, songs of protest and songs of love from one of the essential voices in American poetry.

Floaters takes its title from a term used by certain Border Patrol agents to describe migrants who drown trying to cross over. The title poem responds to the viral photograph of Oscar and Valeria, a Salvadoran father and daughter who drowned in the Rio Grande, and allegations posted in the I’m 10-15 Border Patrol Facebook group that the photo was faked. Espada bears eloquent witness to confrontations with anti-immigrant bigotry as a tenant lawyer years ago, and now sings the praises of Central American adolescents kicking soccer balls over a barbed wire fence in an internment camp founded on that same bigotry. He also knows that times of hate call for poems of love-even in the voice of a cantankerous Galapagos tortoise.

The collection ranges from historical epic to achingly personal lyrics about growing up, the baseball that drops from the sky and smacks Espada in the eye as he contemplates a girl’s gently racist question.

Whether celebrating the visionaries-the fallen dreamers, rebels and poets-or condemning the outrageous governmental neglect of his father’s Puerto Rico in the wake of Hurricane Maria, Espada invokes ferocious, incandescent spirits.
