Levi Johnston is not done baring all.
His story will be revealed in Deer in the Headlights: My Life in Sarah Palin’s Crosshairs, to be released this fall by Touchstone Publishing.
“I want to tell the truth about my close relationship with the Palins,” Johnston, 20, says in a statement released by his publisher. “My sense of Sarah and my perplexing fall from grace – how I feel and what I’ve learned.”
Johnston adds: “I’m doing this for me, for my boy Tripp and for the country.”
