Some couples' cute "how we met" stories involve a walk in the park or a chance encounter at a grocery store. But for Damien Echols, who was on death row for a crime he didn't commit, his first meeting with now-wife Lorri Davis came years after they had begun corresponding with each other. Echols, one of the West Memphis Three, and Davis, who quit her job as a landscape architect to be closer to him, married behind bars in 1999 but couldn't live together as a couple until Echols was finally freed in 2011. Their new book "Yours for Eternity: A Love Story on Death Row" shares their intimate correspondence and tells the story of Echols's life in prison.

"We get asked about our relationship all the time," Davis, 50, tells Yahoo Shine. "Sometimes I'm flabbergasted at the questions people ask us." She first wrote to Echols after seeing the 1996 documentary "Paradise Lost," which detailed the West Memphis Three trial. Echols, along with two other young men, was wrongly convicted of murdering three young boys in their Arkansas hometown, although their real "crime" was simply being rebellious and not fitting in. Echols, then 20, was the only one of the three sentenced to death.

Davis, convinced of Echols's innocence, sent him a letter. Echols was touched and decided to respond. "I just knew that from the very beginning this was someone unlike anyone I had ever known before," Echols says. "It was like she was from a complete different world than I was, and I wanted to see the world through her eyes. When she looked at things and described them they became magical."

Although he was in a maximum-security prison, they were able to write letters and talk on the phone. Soon, they were in love. Davis eventually quit her job and moved to Little Rock, Arkansas, to be closer to Echols, and once they married she was able to take over handling his legal defense. Thanks to celebrity champions like Johnny Depp and Eddie Vedder, there was a renewed interest in the case. A team of lawyers was able to get DNA evidence admitted and new witnesses to testify. Finally, in 2011, the West Memphis Three were released from prison.

For Echols and Davis, finally being able to live together didn't feel like a massive change thanks to the bond they'd already established. "It was seamless," says Davis. "Living together and being together and working together was not a big transition. We did everything we could – we were spiritually and emotionally so connected for so many years because we kept communication going all the time."

Davis, who spent four years corresponding with Echols before telling her family and friends about her relationship, hopes that "Yours for Eternity" will help people see the man she fell in love with. "He's really and truly a throwback to some other time. He's a very traditional gentleman. My dad was like that. Damien is unlike anyone I've known."

And for Echols, who still struggles to cope with PTSD and panic attacks caused from his nearly 20 years in prison (about 10 of which were in solitary confinement), very day with Davis is a blessing. "It's a sense of closure for us," he says about the book's release. "One of the things we tried to do the whole time I was in prison was not focus on the difficulties. If we only focused on that, it would have beat us down and we would not have survived. We tried to focus on the more positive aspects. There were days I got so lost in what we were talking about and the world we were creating that I forgot I was in prison for days at a time."

The couple has since relocated to New York City, where Davis was living when she first saw the documentary that changed her life. They devote themselves to writing and speaking engagements and are working on more creative projects together. They also use their platform to advocate for prison reform.

While Echols, now 39, was in prison, he and Davis would "date" by both watching the same movie or TV show at the same time and then discussing it. Their latest undertaking is a viewing of the prison-set drama "Orange Is the New Black." They'll begin watching it tonight.
