“An absolutely riveting page turner about motherhood, madness, memory and desire set in an ancient mansion that has been thought to be haunted for years. There are definitely many lies being told but you will never guess who the biggest liar of them is and why the lies are being told. The ensemble cast of narrators really helped make the story come alive.”
— Nancy • Fiction Addiction
A lavish, Texas-sized Sweet Sixteen turns deadly in this twisty, pulse-pounding new novel — serving up a fresh take on a classic locked-room whodunnit. Let the festivities begin…
Today is Sophie Matthews’s sixteenth birthday party, an exclusive black-tie bash in the heart of the Texas Hill Country, where secrets are as deep-rooted as the sprawling live oaks. Sophie’s dad has spared no expense, and his renovated cliffside mansion—once thought haunted and shuttered for years from outsiders—is now hosting the event of the season. Then, just before the candles on the three-tiered red velvet cake are blown out, a body falls from the balcony onto the starlit dance floor below.
It’s a killer guest list . . .
DANI: Sophie’s new stepmother who’s been plagued by self-doubt ever since the birth of her own baby girl
ÓRLAITH: the superstitious Irish nanny who senses a looming danger in this cavernous house
MIKAYLA: the birthday girl’s best friend who is not nearly as meek as the popular kids assume
KIM: the cunning ex-wife who has a grudge she can’t let go of . . .
Everyone is invited in. Not everyone will get out alive.

"Party of Liars is my favorite kind of thriller - fun, twisty, fast-paced, and populated by characters who feel so real you'll want to invite them (well, some of them) to your next party. With this debut, Kelsey Cox joins my auto-buy list forever!" - Rachel Hawkins, New York Times bestselling author
"I couldn't put it down! Party of Liars brings the gothic house mystery to Texas, featuring a killer cast, heart-pumping pace, and well-plotted twists and turns." - Nina Simon, New York Times bestselling author of Mother-Daughter Murder Night
"Party of Liars explodes from page one: a stunning debut, a riveting page-turner, a brilliant exploration of motherhood and female desire. Every character is rich and complex, and I was stunned by the jaw-dropping twist at the end. This is the novel I'm always wanting to read: dazzling, terrifying, achingly beautiful. Cox is a major new voice, and I can't wait to read what she writes next." - Amanda Eyre Ward, bestselling author of Lovers and Liars and The Jetsetters
"Party of Liars is Rebecca meets Big Little Lies--an intoxicating alchemy that's haunting, surprising, and eerie. I couldn't put down this searing exploration of madness, motherhood, and memory, set against a jaw-dropping background of Texas wealth and privilege. Kelsey Cox is a stunning talent who brings deep human insight to bear with expertly crafted and unpredictable twists. This is the thriller of the summer." - Katie Gutierrez, bestselling author of More Than You'll Ever Know
"Party of Liars with its stunning prose and simmering tension is a mesmerizing story that's part gothic horror, part psychological thriller, part contemporary glitz—the narrative is masterfully woven with plenty of twists, and deftly handles heavier subjects like postpartum depression, manipulation, and abuse. Kelsey Cox’s debut is exquisite and dripping with dread—I absolutely adored it." - Ashley Tate, international bestselling author of Twenty-Seven Minutes
“Dizzying and dazzling, Cox’s debut slices through the saccharine sweetness of poisonous secrets to reveal the spongy heart of blood-soaked truths… A party to die for.” - Lindy Ryan, author of Bless Your Heart
"With its beautiful but deadly setting and a complex, interconnected web of characters, Party of Liars is a page-turner equal parts juicy and poignant. The mystery is deliciously twisty, anchored by Kelsey Cox's gorgeous writing, but the real heart of the story lies with its complicated women and their sacrifices, both seen and invisible. Secrets and lies abound, readers won't know who to believe, and they will relish every shocking, unpredictable second. I predict this party will be the talk of the town." - Laurie Elizabeth Flynn, author of Till Death Do Us Part and The Girls Are All So Nice Here
