ANCHORAGE, Alaska - Former Republican vice presidential candidate Sarah Palin says she's back on Twitter.

Palin took to the social networking site earlier this year, tweeting about state government, national politics and everything in between.

When she quit as governor in July, she promised she would keep her fans updated through tweets.

But that didn't happen, and Palin communicated with nearly 1 million of her fans on her Facebook page.

But in a Facebook posting Monday announcing more dates on her book tour, Palin says she'll provide Twitter updates from the tour. Her Twitter feed is SarahPalinUSA.

Her book, "Going Rogue," will be published Nov. 17. Her tour starts the next day in Grand Rapids, Mich. There are 13 stops planned before Thanksgiving, including three Florida visits Nov. 24 in Jacksonville, The Villages and Orlando.
