Williams' hardcover book features photos he took from the International Space Station (ISS). Williams, a committed Christian and colonel who has taken more photos from space than any astronaut in history, visited St. Louis on June 17 with his wife, Anna-Marie.

He spoke with about 30 third- and fourth-graders assembled at St. Louis University High School for "NASA: Journey to Outer Space," a day-camp program hosted by the St. Louis Science Center and Mad Science of St. Louis.

Later, Williams screened a video from his most recent missions on the ISS for about 300 employees of Concordia, the publishing arm of the Lutheran Church-Missouri Synod.

Afterward, Williams signed copies of his book at the publisher's bookstore, while a man dressed in a space suit handed out "astronaut ice cream" to children in the store and told them the creation story from Genesis.

Retailing for $28.99, The Work of His Hands discusses what is often viewed as the dueling fields of faith and science. "Good science and the Bible are consistent," Williams said. "I don't see any conflict there."

Williams will sign copies of his book Monday, June 28, at the Concordia booth during the International Christian Retail Show at America's Center in St. Louis.
