Party of Liars by Kelsey Cox Synopsis (from amazon)

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.

“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.” – New York Times bestselling author Rachel Hawkins

“I couldn’t put it down!” – New York Times bestselling author Nina Simon

“Explodes from page one.” – Bestselling author Amanda Eyre Ward

“This is the thriller of the summer.” – Bestselling author Katie Gutierrez

What Is The Book About?

Party of Liars centers on Sophie Matthews’s extravagant sixteenth birthday party, hosted in her father’s grand, cliffside Texas mansion—once rumored to be haunted. Just as the party reaches its peak, a body crashes onto the dance floor, turning celebration into chaos.

This isn’t just a murder mystery. It’s a layered narrative of intertwined lives, hidden grudges, and personal demons. Told through the eyes of multiple female narrators—Sophie’s stepmother Dani, her best friend Mikayla, her ex-wife Kim, and the mysterious nanny Orlaith—the novel explores the dark underbelly of a seemingly perfect family event.

Who Are the Main Characters?

Dani: The overwhelmed young stepmother, battling postpartum depression and paranoia, struggling to balance her dreams and her new chaotic life.
Órlaith: The Irish nanny, superstitious and eerie, convinced that supernatural forces are at play.
Mikayla: Sophie’s best friend, outwardly sweet but harboring secrets that could unravel everything.
Kim: Sophie’s bitter and broken ex-mother, drowning in regret and resentment, with a dangerous grudge.

Why Is This Thriller So Addictive?

1. Multiple Perspectives Keep You Guessing

By shifting viewpoints between key women in Sophie’s life, Cox creates a rich tapestry of motives and emotions. Each narrator reveals personal vulnerabilities and explosive secrets, keeping readers torn between suspicion and sympathy.

2. Deep Themes Beyond the Mystery

This novel tackles motherhood, mental health, jealousy, and female rage with authenticity. The characters aren’t just suspects—they’re human, flawed, and relatable, which heightens the emotional stakes.

3. The Texas Setting Adds Atmosphere

The sprawling mansion and eerie Texas Hill Country setting contribute to a tense, claustrophobic mood perfect for a locked-room mystery with a Southern gothic twist.

4. Pacing and Structure

The story unfolds in near-real-time during the party night, interspersed with flashbacks that peel back the layers of each character’s past. The pacing is relentless, making the tension almost suffocating in the best way.

5. A Jaw-Dropping Ending

Just when you think you’ve figured it out, Cox throws in unexpected twists that keep readers on the edge of their seats until the very last page.
