NEW YORK – Former U.S. Rep. Gabrielle Giffords is working on a book about gun control.

The Arizona Democrat and her husband, the retired Navy captain and astronaut Mark Kelly, are collaborating on “Enough: Our Fight to Keep America Safe from Gun Violence.”

The book, due out in June, is based on an essay by Giffords that appeared in the New York Times last April, when she responded to the fatal shootings of 20 children and six educators in Newtown, Conn., in December 2012. Giffords chastised senators who blocked gun legislation that included expanded background checks and a ban on assault weapons.

“As Second Amendment supporters and gun owners ourselves, we hope our book rouses the long-overdue conversation our country needs to make responsible changes to our gun laws so that no more precious lives are lost,” Kelly said in a statement.
