As featured in The New York Times’ “Best Mysteries of the Month” and Parade Magazine‘s “Six Books You Should Read if You Love Stranger Things!“

With this novel I set out to write a different kind of mystery, one that is spooky & fun and brings to life an imaginary version of a real place: Soap Lake, WA. I’m thrilled to be working with a publishing team that wanted to capture that vision with a distinctive wraparound cover… a sort of narrative map, encompassing the physical book in the same way that the place encompasses the story.

“Matthew Sullivan has crafted a brainy thriller that conjures the mischievous humor of Lynch, while imagining conspiracies more unspeakable than Chinatown. His spiderweb of a plot, deeply felt characters, and enchanting love of science will have me dreaming about Soap Lake for a long time. This is my kind of weird.”
–Nova Jacobs, author of THE LAST EQUATION OF ISAAC SEVEREY and THE STARS TURNED INSIDE OUT
“Midnight in Soap Lake is a swirling story for readers who like their dark tales moderated by compassion. Matthew Sullivan has created a town populated by a wild and motley cast—the flawed, the fallen, the damaged and deranged.

And as all the colorful threads in this delightful novel converge, the tale heads for a dazzling, bittersweet conclusion.”

When Abigail agreed to move to Soap Lake, Washington, for her husband’s research, she expected old-growth forests and craft beer, folksy neighbors and the world’s largest lava lamp. Instead, after her husband jets off to Poland for a research trip, she finds herself alone, in a town surrounded by sand and haunted by its own urban legends.
But when a young boy runs through the desert into Abigail’s arms, her life becomes entwined with his and the questions surrounding the death of his mother, Esme. In Abigail’s search for answers, she enlists the help of a recovering addict turned librarian, a grieving brother, a broken motel owner and a mentally shattered conspiracy theorist to unearth Esme’s tragic past, the town’s violent history and the secret magic locked in the lake her husband was sent there to study.
As she gets closer to the answers, past and present crimes begin to collide, and Abigail finds herself gaining the unwelcome attention of the town’s unofficial mascot, the rubber-suited orchard stalker known as TreeTop, a specter who seems to be lurking in every dark shadow and around every shady corner.
A sweeping, decade-spanning mystery brimming with quirky characters and puzzle-hunt scenarios, Midnight in Soap Lake is a modern-day Twin Peaks—a rich, expansive universe that readers will enter and never forget.
