They took her freedom and her liberty. They should have taken her life.

Alex Ridley knows there are only three certainties in life … taxes, death, and that if you kidnap and hurt girls and young women? She will hunt you down, and she will end you!

Alex Ridley has changed. She was once a respected art historian. A pacifist. Flawed, yes. Troubled, certainly. Now she's driven to do whatever it takes to bring down the traffickers, including acts of extreme violence. She'll track them to their dens. She'll play them at their own heinous game. She'll turn justice into a masterpiece.

From India to Tibet, and then Milan, Ridley's fierce determination to administer justice and liberate the victims—women and girls, just like her—thrusts her into the chaos of Marrakesh.

She thought she'd seen the very worst of humanity. The 'Red City' opens her eyes to new levels of depravity.

Ridley must survive. Hundreds—thousands—will suffer if she doesn't. Yet, up against the most dangerous enemy she's ever faced, the odds are stacked against her.

She hates them. To defeat them, she must become them.
