“I will get stronger,” she writes. “I will return.”

But the Arizona Democrat did not specify when that return is likely to be. Should Giffords choose to run for office in 2012, the filing deadline is in March of next year.

The congresswoman returned to the House in August to cast a vote in favor of the debt-ceiling deal, an emotional appearance where she was met with a standing ovation.

But staffers for the lawmaker have repeatedly tamped down speculation about her political future, saying that her recovery is a slow process. And the AP reported that the congresswoman’s book states that Giffords has lost 50 percent of her vision in both eyes.

The book also reveals that Giffords and her husband, former astronaut Mark Kelly, were “quietly trying to a have a baby” before the shooting occurred, according to the AP.

Giffords also spoke with ABC News’ Diane Sawyer, for a television special that will air on Nov. 14 — her first comments to the media since the shooting. It will not, a spokeswoman said, be “a full-length interview.”
