Leading conservative radio host and author Mark Levin has been greeted with long lines of eager buyers at book signings for his latest, "The Liberty Amendments," but his biggest sale just came in via Facebook: Sarah Palin just touted it as a "real solution" to restore the nation.

On her page she included a picture of her in a four-wheeler. Under it, Palin, the former Alaska governor and 2008 Republican vice presidential nominee wrote:

"I'm just waiting for the guys to finish loading up gear, so I'm using the 'wait time' to finish reading Mark Levin's great new book 'The Liberty Amendments.' It offers a real solution and way forward to restoring our republic. Please get this book, read it, and let's make it happen!"

In the book, Levin suggests that states call a constitutional convention to address amendments like his that would address term limits, taxation, states' rights and more.
