It was a time of social turmoil.

The working man wanted his voice heard in government. The Chartist movement was met with a violent reaction from the powers that be; the leaders were imprisoned or they fled the country.

It was an age of science.

Gentlefolk became amateur naturalists, collecting specimens of life living and dead. Fossil discoveries caused great wonder. Theories were created to explain the fossil records, some contorted to fit the Christian idea of time and history. Scandalous books were published suggesting a natural history that upset the Christian hegemony.

My Victorian Age professor had our class read pivotal books published in 1859, including The Origin of Species by Charles Darwin. The professor told us that the ideas behind Darwin's book had been around; Darwin's genius was to put the puzzle pieces together, grounded in sound scientific research. Darwin dragged his feet publishing his theory, knowing the havoc it would bring.

The Great Unknown by Peg Kingman is set in 1846 when people were beginning to think about the questions Darwin finally, publicly, addressed in 1859.

There is a mysterious woman at the heart of the novel who goes by the alias Mrs. McAdams. She left her husband and traveled to the city to give birth to twins, one of whom died a month later. She is enlisted to be a wet nurse to a brilliant family who warmly welcomes her.

Mrs. McAdams struggles with issues of identity. Her mother's early death left clouded her true paternity. And she wonders about the big questions: are we ruled by chance, nature, or God? What does it mean to be human? What separates us from other creatures?

Several books are central in the novel, books that arouse deep thoughts from the characters. One is the 1845 best-selling, iconoclastic Vestiges of the National History of Creation. Another is the 1831 On Naval Timber and Arboriculture, which sounds like a yawner, but its appendix included a discussion of natural selection.

Vestiges became a best-seller. It appears and reappears in the novel, traveling from hand to hand.

They were dangerous things, book; best locked safely away in cages, like fierce beasts in a menagerie. ~from The Great Unknown by Peg Kingman

Mrs. McAdams's backstory is slowly revealed. Her quest to find her natural father takes her on an interesting and surprising journey. She questions many things--why a baby with extra digits is not embraced as an evolutionary improvement; whether things happen by chance or design; if humankind has the power--clearly, it does have the will--to reverse the spinning of the galaxies.

The Great Unknown is an idea-driven story, and I found myself intrigued to read on for the questions posed are timeless.

As a quilter interested in quilt and fiber history, I was interested in Mrs. McAdam's vocation creating 'bizarres', designs for roller-printed cottons that were popular in the 1840s. Her designs were inspired by the minuscule life she discovered under the powerful new microscopes. Science had even invaded fashion! Colors, too. The newly discovered aniline dyes replaced the plant-based dyes, and new colors rose to popularity: mauve and purple, chrome yellow and orange, and greens that did not fade to blue or tan or rely on arsenic.

Our heroine's journey takes her into her past to discover her true family roots before she returns to her husband. All their hopes are realized in a strange and circular way in a satisfying resolution.

In the 19th c, science was embraced as a panacea to society's ills, a way to reverse the natural order. Science disturbed the status quo and challenged Biblical authority, upended humanity's place in the universe and scheme of things.

But as Mrs. McAdams and we know, it appears that chance is what really rules the universe.

I was granted access to a free ebook by the publisher through NetGalley. My review is fair and unbiased.

The liberal, indeed revolutionary, household of the Chambers family is the perfect temporary home for Constantia. Living under an assumed name, temporarily in Edinburgh to deliver her babies, she acts as wet nurse to Mrs. Chambers newborn son. The new state of motherhood brings back vividly Constantia’s color and scent-filled memories of her childhood living in India with her mother. The lively intellectualism of teatime in the busy Chambers household encourages her to question origins: of birth, of books, of the natural world itself. Do they matter? Is illegitimacy a sin? Does the author of a book change the book itself?

I raced through the end of the novel to know the outcome of the story, but then immediately returned to the beginning to savor the beautiful passages describing its people and places. A 5*+ read.

I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own.
