Cheney has slowly reemerged into public life since his heart transplant surgery earlier this year. In July, he hosted a $30,000 per plate fundraiser for Mitt Romney at his Wyoming home.

Cheney suffered five heart attacks throughout his life, and used an electronic pacemaker before his heart transplant surgery in March. Cheney had been on the donor wait list since June 2010.

The former vice president has been outspoken about his heart treatments in the past, famously disconnecting his battery-operated heart pump during a segment on the "Today Show" in 2011. He told the Times that the idea for the book came during an appearance with his cardiologist at the Cleveland Clinic.

Cheney called his recovery "nothing short of a miracle."

"I'm better than I've been in years," he said.
