Tell me more about Alex

She has built the life she always wanted. Someone is determined to tear it apart.

Alex Demarchelier is a successful international designer with a flourishing career and a new love that feels almost too good to be true.

It is.

Her lover’s estranged wife, Vivien, refuses to accept that their marriage is over. Behind an ordinary suburban façade lurks a master manipulator who considers Alex responsible for everything missing from her life—and who believes revenge is her right.

At first, the attacks seem personal: malicious rumors, false accusations, disturbing intrusions, and calculated attempts to turn the people Alex loves against her. Then the danger spreads. Private information is weaponized. Money disappears. Identities become unreliable. Digital trails lead nowhere.

As Alex struggles to protect her career, her relationships, and her sanity, she discovers that Vivien may not be acting alone. The vendetta surrounding her is connected to something far more organized—and far more dangerous—than one woman’s obsession.

To survive, Alex must stop reacting to the traps laid for her and uncover the machinery behind them.

But how do you fight an enemy who can reach into every part of your life while remaining almost invisible?

And who is Vivien?

A Formidable Villain Who Believes She Is the Victim

Vivien does not see herself as cruel. She sees herself as wronged.

She reshapes facts, exploits sympathy, recruits other people into her battles, and treats every consequence of her own behavior as further evidence of persecution. Her ability to defy reality makes her unpredictable—and exceptionally dangerous.

The result is a psychological contest in which Alex must defend herself not only against what Vivien does, but against the false version of Alex that Vivien persuades others to believe.

The Wall: An International Thriller with an Intimate Core

From Montreal and Dallas to Houston, Dubai, Nepal, and the Caribbean, The Wall moves through a world of ambitious architects, technology entrepreneurs, political insiders, and hidden operators.

Yet the central questions remain deeply personal:

How much of yourself can you lose while trying to preserve a relationship?

When does compassion become complicity?

How do you defend yourself against someone who uses your decency as a weapon?

And what happens when a lie travels faster than the truth?

I love storytelling and exploring what people do when life pushes them to the edge.

My fascination with why some people crumble under pressure, others become villains, and some rise to become their best selves found its way into all my books. I hope you’ll enjoy the characters' journeys through fear, conscience, and the darker corners of the human psyche.

My husband and I live in Baltimore.
