Saved By the Enemy by Emma Roberts

Don’t count on rescue from a lover-turned-enemy.
Especially when he’s marrying another woman.
Captured by my blackmailer, I end up in France.
But nothing is exotic about being sold at f@cking auction.
I have to escape.
It’s all on me now.
Logan Farraday—my enemy and the only man I’ve ever wanted—can’t save me now.
But a girl can dream.
When he turns up, hot on my trail, I can hardly believe it.
My mission is clear. I have to bring my blackmailer down, for good.
But this trafficking ring goes deeper than anyone ever imagined.
The ramifications could be catastrophic, and so could my secret.
One more mission with the man who makes me burn.
Can I keep this dangerous man in my bed for good?
Will we both live to find out?
