— Republican Mark Sanford, the former South Carolina governor whose extramarital affair derailed his political career, returned to Congress Wednesday.

How to buy the Sanford e-book

A new e-book, “Second Chance: The Mark Sanford Story” will be on sale soon at Amazon, iTunes and other e-reader formats. Check Evening Post Books for availability. “Second Chance” is part of a new publishing trend to produce “e-shorts” — stories that are too long to run in a newspaper and too short to be books.

They are designed to be read in one long sitting and give readers a vivid picture of an issue or, in this case, a public figure’s riveting internal struggle.

“I do,” Sanford said, taking his oath.

“Congratulations, you are now a member of the 113th Congress,” House Speaker John Boehner said.

With that, the saga of the gifted politician, husband and father who served three terms in the House beginning in 1995, went on to become governor and threw it all away for his now-fiancee Maria Belen Chapur, came full-circle.

A week earlier he had defeated Democrat Elizabeth Colbert Busch, the sister of political satirist Stephen Colbert, in a special election for the 1st District.

“I’m simply humbled to be here,” Sanford told the House, noting two sons watching from the gallery, along with Chapur. “I stand before you, I guess, with a whole new appreciation for a god of second chances.”

Sanford’s return sets up an awkward dance with congressional Republicans, but on Wednesday, everyone was pledging to work together.

“If there’s anybody who believes in putting the past behind them, it’s me,” Sanford told reporters. “I don’t begrudge anybody for doing what they felt they needed to do at a given moment in time. I look forward to working with each of them.”
