On August 10, 1999, Donna Dees-Thomases watched as every parent's nightmare unfolded on TV

: A gunman had shot and injured two young children at a California day camp. "My heart was in my throat," she says. "Those children could have been mine."

Anger and fear led Dees-Thomases, 46, a mother of three from Short Hills, NJ, to organize the Million Mom March on Mother's Day in 2000. A stand against the 30 000 deaths and 75 000 gun-related injuries a year in the United States, it drew an estimated 750 000 to Washington, DC.

Now the second Million Mom March, set for May 9 in DC, will urge the federal government to renew and strengthen the assault weapons ban (set to expire in September). And Dees-Thomases' new book, Looking for a Few Good Moms: How One Mother Rallied a Million Others against the Gun Lobby, will be published this month by Rodale, Prevention's parent company.
