Book excerpt: Poetry. Written under the spell of a medieval Welsh poetic form, the poems in Anthony Madrid's incantatory second book, TRY NEVER, each offer up their own strange world. They're full of erudition, humor, and rare magnificence. A single poem can contain "bottles and cans," Mount Everest, an upset stomach, Texas rain, a hawk, the evil queen, a "twice- mended lid," and Ralph; as if to say, anything's possible.
