(CNN) - Gov. Mark Sanford and his publisher have parted ways.
"Sentinel has agreed to release Governor Mark Sanford of South Carolina from his contract to write a book about fiscal conservatism, which was to be called WITHIN OUR MEANS and was scheduled for publication in March 2010," said Adrian Zackheim, president and publisher of Sentinel, in a statement released Thursday. "This is a mutual decision. We wish Governor Sanford the best."
Prior to revelations of an extramarital affair that effectively brought an end to his political career, the South Carolina governor had been preparing to publish a book outlining his policy beliefs.
Sentinel, a conservative imprint of Penguin Group, had included the Sanford book in their Spring 2010 catalogue. It was described by the publisher as "a manifesto about fiscal conservatism – why the government needs to spend less and fix the deficit ASAP."
Sanford's office has not commented about the book deal, or about its collapse.
