Book excerpt: Poetry. Asian American Studies. Jenna Le's debut book is a meditation on love and life, as refracted through the waters of six rivers, ranging from the mighty Mississippi River to the gloomy River Styx. Inspired by her experiences as a Vietnamese-American woman who earned a degree in mathematics before becoming a physician, these poems are sometimes autobiographical, sometimes based on flights of imagination. Peopled by a diverse array of characters drawn from the pages of history and mythology (including the computer programmer Ada Lovelace and the sculptor Louise Bourgeois), and displaying familiarity with a broad gamut of forms ranging from the European sonnet to the Asian haibun, this sensual and often funny book introduces a strong, original new voice in poetry.
