A young mother from Portland, Maine, who was struggling with kidney failure and waiting with little hope on the transplant list came up with a unique idea.

Christine Royles, who was diagnosed with both lupus and ANCA vasculitis, posted a heartfelt plea for a kidney donor on the rear window of her car.

"My 2-year-old son needs a healthy mom! Looking for a type O blood kidney. I am 23 on dialysis. Call or text," Royles wrote.

Incredibly, a stranger saw her mobile ad and offered to help.

Josh Dall-Leighton has been classified as a strong match and the kidney transplant surgery is set for May.

Royles and Dall-Leighton spoke to Brian Kilmeade on "Fox and Friends" about this amazing and surprising gift of life.

"I had a really good feeling inside that it was going to work, but I didn't expect to get as many responses as I did," Royles said. "My family is super-excited because they feel like we're getting an extension of our family by meeting Josh and his wife."

Dall-Leighton, a father of three, explained that having kids of his own really made Royles' message resonate with him.

Royles said that since Dall-Leighton won't be paid while he misses three to six weeks of work after the surgery, she organized a fundraising pancake breakfast to help raise money. There's also a GoFundMe page to help cover his family's expenses during that time.

"At first, my family was a little apprehensive," Dall-Leighton revealed. "But they know me, they know my character, and I really want to do this to help her out."
