But off-camera, the couple carried a dark burden: a mysterious illness that had plagued Erin for a decade and threatened to prevent her from having children. The Napiers opened up about the experience in their memoir Make Something Good Today, out now. "It was a really sad and scary and confusing ten years," she tells PEOPLE in this week's issue.

"In the beginning, it would be 24 hours of terrible stomach pain and a low-grade fever, and then it would disappear," Erin recalls. But the episodes only grew more intense after she married her college sweetheart Ben, a carpenter and former youth pastor, in 2008. "It became two days, then three." At its worst, she would be laid up for a week at a time, unable to move without pain and without any idea what was causing it. "We went through everything, from doctors thinking it might be something really bad like cancer to saying it was in Erin's head," Ben recalls. Countless tests and CT scans never showed anything out of order.

Baffled by the finding, they sent her to another surgeon. Simon & Schuster/Gallery Books During a second procedure, doctors discovered the cause of the extremely rare condition: a perforated appendix. The organ had been bursting and healing itself repeatedly for years. "The first time it happened, when I was 19, it just partially ruptured. Not enough to kill me, just enough to make me sick," Erin says. The organ had healed itself, becoming encased in scar tissue that eventually spread "like a cancer" to cover her other internal organs. Even after removing the tissue and her appendix, Erin was told having children "wasn't likely," due to the damage caused over the years. The couple knew they wanted to start a family, but Erin had harbored a fear of childbirth, "the surgical aspect of it," she says. Ironically, undergoing the emergency procedures, eased her fear to an extent. "I was very sad. And not knowing is always the biggest hurdle for me to overcome. I like to have proof. And we had no proof that I would be able to have kids," she says of their journey to parenthood. Amazingly, the Napiers were surprised to find out that they were expecting three years later — on Mother's Day 2017. The happy couple welcomed their first child, a daughter named Helen, this past January.

"Helen is a joy in every way. She's kind of the best. She's the best baby ever."
