The president's most vocal critic against the war in Iraq was in the Capitol City Wednesday night.

Cindy Sheehan was at BookPeople on Lamar & 6th Street signing autographs for her new book entitled "Peace Mom".

Sheehan's son, Casey Sheehan, died while on patrol in Iraq on April 4th, 2005.

“Whether you agree with it or not, I think we should all be reading books by the families of people who've loss their sons and daughters in this war,” said Turk Pipkin, who was buying one of Sheehan’s books.

Sheehan bought a house in Crawford where she and her supporters often protest near President George Bush's ranch.

"What I really hope to do with it is to inspire people to do what they can to make the world a better place and to let them know that one person really can make a difference," Cindy Sheehan.

Sheehan also announced at the signing that she's a finalist for a Nobel Peace Prize.
