Kiss Me Harder by Aja Cole

Naja Quentin is no stranger to arrogant men.
So why can’t she shake one annoying FBI agent by the name of Elias Samir? The man is relentless, sexy as hell and way too idealistic for them to work. There’s far too much at stake for her to fall in love, but even when she tries to lock her feelings securely away…the damn things just keep finding the key!

What’s a girl to do?
Elias Samir was a goner the minute he laid eyes on the golden-eyed field operative with pain behind her eyes.
She radiates strength with a healthy dose of danger, and what man can resist a badass who can kick his ass and look damned appealing doing it?

Now, he needs her help, but two stubborn people is one too many.
One wants justice.
One wants vengeance.
They say that when you start a quest for revenge, you should dig two graves…
Will they need more?
