DALLAS (AP) Former first lady Laura Bush has announced the authors set to attend the Texas Book Festival, a lineup that will include Jewel, Junot Diaz and Tim O'Brien.

Bush, who founded the festival when she was first lady of Texas, also unveiled Wednesday the festival poster designed by Texas artist Margie Crisp featuring cliff swallows flying over the Colorado River.

Crisp, author of "River of Contrasts: The Texas Colorado," will participate in the festival set for Oct. 27-28 at the Texas Capitol.

Bush, who made the announcement in the backyard of her Dallas home, said, "We have a really wonderful lineup once again."

More than 40,000 people are expected to attend the free event that includes author readings and presentations, panel discussions and book signings.
