The term "half-life" is used to describe radioactive decay, pharmaceutical drugs, rocks, the atoms of our human bodies, and even technological products. Using this idea as a starting point, A Half-Life provides a rare glimpse into the Korean American experience. The poems utilize the literal metaphor of the highway as the intersecting point of America, Asia, and the globe, to reflect on the emotional and physical journeys many Asian Americans take. From Chicago to Seattle, from the biographical to the fictional, from current times to the Korean and Vietnam wars, A Half-Life covers the joy and pain, the probable and improbable, the individual and communal--the cultural histories we all share.
