Sixteen years behind a desk made Madison Sinclair forget how dangerous desire can be.

Now she's trading soccer mom respectability for the shadowed decadence of Nox Venari?the world's most exclusive playground for the powerful and depraved. Her mission: become irresistible to Prince Zaydan al-Kharabati, the ruthless head of an international terror network, who hunts married Western women like prey, breaking them for sport.

The bait? Madison herself?wrapped in silk and sin, playing the bored wife seeking forbidden thrills.

Prince Zaydan holds the key to Null:Echo, a quantum weapon that could plunge the world into chaos. The exchange will happen inside Nox Venari's velvet shadows, where temptation lurks around every corner, inhibitions shatter, and Madison must surrender everything to get close enough to strike.

But seduction is a blade that cuts both ways. As Madison descends deeper into the prince's twisted games?with Damien watching, wanting, remembering?she discovers the most dangerous territory isn't the mission. It's how much she's willing to sacrifice.

Madison will put everything on the line for her country and her family, knowing that success could mean losing everything. Undercover Wife: Scarlet Phantom is the third book in the Undercover Wife series!
