father's letters, Jennifer Tseng's Thanks for Letting Us Know You Are Alive is a portrait of an immigrant, a rootless person whose unspoken loss--that of his native geography, family, traditions, language--underlies every word. Though her father's first language was Mandarin, for more than twenty years he wrote these letters in English, so that she could understand them. Some are riddled with errors, some nearly unintelligible. Lines from his letters appear as titles and are scattered throughout the poems, blending voices of father and daughter. This collection enacts what it means to lose someone and commune with them simultaneously--the paradox of grief and all it gives us.
