Newshub was given an advanced copy of the book which spurred the first edition of Newshub Story Time, featuring Patrick Gower, Samantha Hayes and Mike McRoberts.
The story of the two Hereford cows and a calf stranded on an island of grass made headlines around the world in November following the magnitude 7.8 Kaikōura quake.
They became the faces of the severely damaging quake, the aftermath of which is still being slowly cleaned up.
Their story captured the imaginations of many, with some creative people penning poems, writing songs, drawing pictures and even sending letters from around the world in awe of the cows' journey and wishing Ms Millton and husband Derrick well.
Ms Millton says the story came to her on a sleepless night following the quake. She jotted down some words on the back of an old calendar in about an hour.
"It must have been at the time the cows had been rescued and I must have been thinking about it and a little ditty came into my head and I wrote it," she says.
It was important to her the story was factual and identifiably the Kaikōura area. The book depicts the Clarence Valley where the Milltons have farmed for 90 years, the mountains and sea coast, the "big white slip" and the Hereford cows.
The book, published by Allen & Unwin, goes on general sale on Friday.
