J.r. Ward said this quote

When her blue-black eyes lifted to his, everything disappeared. Their bodies dematerialized. The room they were in ceased to exist. Time became nothing. And in the void, in the wormhold, Wrath's chest opened up sure as if he'd been shot, a piercing pain licking over his nerve endings. He knew then that there are many ways for a heart to break. Sometimes it's from the crowding of life, the compression of responsibility and birthright and burden that just squeezed you until you couldn't breathe anymore. Even though your lungs were working just fine. And sometimes it's from the casual cruelty of a fate that took you far from where you had thought you would end up.And sometimes it's age in the face of youth. Or sickness in the face of health. But sometimes it's just because you're looking into the eyes of your lover, and your gratitude for having them in your life overflows...because you showed them what was on the inside and they didn't run scared or turn away: they accepted you and loved you and held you in the midst of your passion or your fear...or your combination of both. Wrath closed his eyes and focused on the soft pulls at his wrist. God, they were just like the beat of his heart. Which made sense.Because she was the center of his chest. And the center of his world.
