A simple DNA test is all it takes. Just a quick mouth swab, and soon, you'll be matched with your perfect partner - the one you're genetically made for. That's the promise made by Match Your DNA. A decade ago, the company announced that they had found the gene that pairs each of us with our soul mate. Since then, millions of people around the world have been matched. But the discovery has its downsides: Test results have led to the breakup of countless relationships and upended the traditional ideas of dating, romance, and love.

Nineteen-year-old Signa Farrow, orphaned as a baby, has been raised by a string of guardians, each more interested in her wealth than her well-being—and each has met an untimely end. Her last remaining relatives are the Hawthornes, an eccentric family living at the glittering and gloomy estate of Thorn Grove. Thorn Grove’s patriarch, Elijah, mourns his late wife, Lillian, through wild parties and drink, while eldest son Percy grapples for control of the family’s waning reputation and daughter Blythe suffers from the same mysterious illness that killed her mother.

Deep in the heart of Appalachia stands a crooked farmhouse miles from any road. The Morrows keep to themselves, and it's served them well so far. When girls go missing off the side of the highway, the cops don't knock on their door. Which is a good thing, seeing what's buried in the Morrows' backyard. But 19-year-old Michael Morrow isn't like the rest of his family. He doesn't take pleasure in the screams that echo through the trees.

This forest isn't charted on any map. Every car breaks down at its treeline. Mina's is no different. Left stranded, she is forced into the dark woodland only to find a woman shouting, urging Mina to run to a concrete bunker. As the door slams behind her, the building is besieged by screams. Mina finds herself in a room with a wall of glass, and an electric light that activates at nightfall, when the watchers come above ground. These creatures emerge to observe their captive humans and terrible things happen to anyone who doesn't reach the bunker in time.

Kate Sedgwick’s life has been anything but typical. She’s endured hardship and tragedy, but throughout it all, she remains happy and optimistic (there’s a reason her best friend Gus calls her Bright Side). She’s quick-witted, endlessly passionate about music, the first to offer a smile, and the kind of loyal that most friends only dream about. The one thing that escapes her optimism is love. She’s never bought into it. So, when Kate leaves San Diego to attend college in the small town of Grant, Minnesota, the last thing she expects is to fall hard for Keller Banks.
