Simon & Schuster isn’t going to let the clock run out on Levi Johnston’s 15 minutes of fame.

The publisher announced on Monday that its Touchstone imprint had signed a deal with the father of Sarah Palin’s grandson to release his memoir this fall. In “Deer in the Headlights: My Life in Sarah Palin’s Crosshairs,” Johnston promises to “set the record straight” about the Palin family.

“I want to tell the truth about my close relationship with the Palins, my sense of Sarah, and my perplexing fall from grace — how I feel about what I learned,” Johnston said in a press release. “I’m doing this for me, for my boy Tripp and for the country.”

Johnston’s rocky teenage relationship with Bristol Palin was a sideshow event of the 2008 presidential election. Last year, he posed for Playgirl magazine and she appeared on “Dancing with the Stars.”

“This is a sweet and funny book with a touch of irony; a fascinating tale of a misunderstood boy figuring out how to be a man and father after being thrust into the spotlight and subsequent media circus at a very young and vulnerable age,” said Stacy Creamer, vice president at Touchstone.

Bristol also has a memoir coming out. “Not Afraid of Life: My Journey So Far” will be released on June 21.
