Nightingale by Andrea Bramhall

When Charlie Porter meets Hazaar Alim her first year of university, she's instantly smitten. Hazaar has it all: beauty, talent, and brains. What she doesn't realize is that Hazaar's future has already been decided, and Charlie has no place in it.

Hazaar desperately wants to break with her traditions and stay with Charlie, but when forced to choose, she chooses her family over love. When she realizes the choice she made is the worst one possible, it's too late.

Years later, while working in Pakistan as a diplomat and negotiator, Charlie receives a phone call from a woman who says her British sister-in-law is to be killed for the family's honor and asks if someone can save her.

Charlie and Hazaar are on a collision course with destiny. If they make it out alive, can they believe in their love once again?
