(PEOPLE.com) -- Elizabeth Edwards -- and, for the first time, daughter Cate -- are opening up about John Edwards's infidelity and the breakup of the marriage.

In PEOPLE's edition next week, Cate, 28, who lives in Washington and clerks for a federal judge, and her mother talk candidly about their relationships with John now, Elizabeth's cancer and other issues.

"There are the things she taught without words," Cate writes about her mother in a bonus essay for PEOPLE. Like, "how to continue to live your life on your own terms when it somehow becomes savaged by people you never invited into it."

PEOPLE's extensive interview was Elizabeth's first in more than a year and her first public comments since several tell-all books and interviews about the former presidential candidate's affair called Elizabeth's own character into question earlier this year.

"It's my story and I'm writing it from here on out -- nobody else," Elizabeth says in the interview as the paperback edition of her bestselling book "Resilience," is released.

The paperback includes a new chapter reflecting on the worst of the fallout from husband John's infidelity and on their split at the end of last year.
