In the summer of 2014, the two prayed a novena to St. Anne.
"She and I would meet up at the adoration chapel and talk about the reflection of the day and it would be about all these feminine virtues," Finegan said.
"We were like yelling at each other, agreeing, but yelling because we were so passionate about it," Koslosky said.
The idea of doing something about it popped up, but was forgotten as time went on. It was not until the Feast of the Assumption on August 15 of that year, that it resurfaced.
The two women were in the car driving to Mass when Koslosky began talking about how she loved the books she was reading on feminine virtue.
Finegan said she loved those books too but they would always lose her attention part-way in and that, "honestly, I feel like we need someone in our generation to write to us because I'm tired of 40-year-olds writing to us when really, our generation is different."
They pointed out that the culture of dating had completely changed and with the influence of technology, everything was different. The two agreed that someday a college student should write a book when Finegan said, "I feel like we should do that."
"I was like, 'Nope, do you know what it means to write a book?'" Koslosky recalled.
"That's long. We are busy people," she said.
That fall semester, Finegan was leaving for a study abroad trip in Florence, Italy and Koslosky was getting ready to coordinate a large retreat for her college's campus ministry. They were both loaded up on school credits and said they did not have the time.
But they prayed about it that day and said, "It was a weird Mass experience."

Koslosky said she began to laugh and was full of joy. She thought, "We have to do this." Finegan said she knew God was asking a lot and she was scared, but once she gave it all to Him, she had peace about the idea.
"Both of us were dead in," they said.
As Mass continued, they began to write things down on a little notebook Koslosky had in her purse.
"We get to her [Kaylin's] home and we just like start looking at what we had written down and we typed it up and we had an outline and intro done," Finegan said.
Neither of the young women were writers, but they said journaling was how they prayed best. During the fall semester, they tried writing more, but it was not very productive. So that Christmas break, they gave themselves one week to get it all done.
"Each day we wrote a section," Koslosky said.
