The Lines We Cross by R. L. McCalla

If DNA is the blueprint of life, what happens when we change the instructions?
When deputy Sam Thurston responds to a report of a dead body on the side of the road, he’s completely unprepared for what he’ll find: a pregnant woman, womb cut open, baby missing. So soon after his own wife’s miscarriage, Sam is drawn in to the case. In his search to find both the baby and the young woman’s killer, Sam uncovers a hidden world of rogue scientists, genetic editing, and pregnant college students.
Meanwhile, Ava Newman learns she’s pregnant, accepts a scholarship to a school founded by a biotech billionaire, and unknowingly moves into the room previously occupied by the roadside victim. There, Ava discovers secrets about life and death and her own DNA.
In order for Ava and Sam to uncover what really happened, they must confront their fears, their families, and secrets someone is willing to kill for. Lives are not the only thing at stake. They’re fighting to determine what it means to be human.
MY REVIEW
The Lines We Cross is in my top twenty if not top ten books of the year. I loved this book.
I’m familiar with this author and read many of her previous works with Harlequin so The Lines We Cross was a surprise to me. It challenged everything I though I believed about DNA, science, gene editing and life. I came away from this mystery changing my mind about various scientific studies, and it left me with certain what-if’s.
I could not put this mystery down. When does science go too far? What are the repercussions on those left behind or those coming after us in the future? And then…what part does faith play in this? Can science and faith come together? Or is faith a separate entity? Who are we as people and what dictates the choices we make? Do we throw aside faith when questioning how far is too far if the end justifies the means and it makes a difference in our health and safety? I thought I was pat in my answers to those questions until I read this book and made me look at why I believed what I believed.
And yes, this is a mystery, and it is fiction and it is a page turner. Find out for yourself. So far, my best book of this year.
