Book excerpt: Jimmy Santiago Baca continues his daily pilgrimage through the meadows, riverbanks, and bosques of the Rio Grande where winter dies, spring explodes, and inextricable links between the human spirit and the natural world are revealed, chronicling and expanding upon those in his recent Winter Poems Along the Rio Grande. In Spring Poems the words of the river "rise around thorny thickets / then descend again into the burbling stubble," and the poet surrenders himself to this place where his own words are woven by "a thumbnail-sized yellow spider/ with poppy seed eyes."--Amazon.com.
