rto's dazzling debut collection, we hear the voice of the recurring angel figure for the first time, commanding us to "Get used to the light." That light-blinding, mysterious, unsettling, but occasionally illuminating-shows up again and again in Porto's taut, elegant poems. As he writes in another poem: "Some light, it's true, makes it to us, but always / refractory, errant, struggling to deign downward."

The occasions for these poems range from encounters with ancient biblical and mythological tropes to fresh translations of elegiac Anglo-Saxon verse to sojourns from Texas to Taiwan and Vermont to Venice.

Holding everything together-the themes of love and responsibility, memory and forgetfulness, loss and hope-is the grammar of the moon, ever-changing, yet ever-present. Here is a fully mature poetic voice, one which former U.S. Poet Laureate Robert Pinsky rightly hails as "ingeniously alert, compelling, and unpredictable."
