(CNN) - Sarah Palin's heading to Iowa.
The former Alaska governor and 2008 GOP vice presidential nominee's upcoming book tour will taker her to Sioux City, Iowa, on Sunday December 6, according to an announcement posted on the Barnes and Noble Web site.
Palin will kick off the tour in Grand Rapids, Michigan on November 18, one day after her book, "Going Rogue: An American Life," is released.
Iowa's caucuses traditionally kick off the presidential primary season and any appearance in the Hawkeye State by a Republican who may be considering a run for the 2012 GOP presidential nomination sparks speculation.
Sioux City is in the heart of the conservative northwest part of Iowa.
Palin isn't the only possible Republican White House hopeful making an appearance in Iowa. Mike Huckabee, the former Arkansas governor and 2008 Republican presidential candidate, visited three bookstores in eastern and central Iowa on Sunday to sign copies of his new holiday themed book. And Minnesota Gov. Tim Pawlenty was in the state Saturday to give the keynote address at a major Iowa Republican party dinner.
