Luci Tapahonso returns to Lawrence to launch “A Radiant Curve: Poems and Stories.” She will hold a free public reading at 7 p.m. today at the Lawrence Arts Center, 940 N.H. In this sixth collection of stories and verse, Tapahonso finds sacredness in everyday life. Viewing a sunset in a desert sky, listening to her granddaughter recount how she spent her day or visiting her mother after her father has died, she finds traces of her own memories, along with echoes of the voices of her Navajo ancestors. Originally from New Mexico, the former Kansas University professor now teaches American Indian Studies and English at the University of Arizona. She is the author of three children’s books and six books of poetry.
