Quickly Falling in Qatar (Ticket to True Love)
Christi Snow, Ticket TrueLove

Nine years later, Petra has a good life as an FBI agent. She helps find missing people and has found her own semblance of peace. But that’s all thrown into chaos when her new assignment pairs her up with the ex she let slip away...Mal.
They’re undercover in a foreign country looking for a missing soldier, and worse—they’re forced to pose as a couple in love.
The problem...the lie may be closer to the truth than either one of them wants to admit, especially with so many hurts and secrets still standing between them.
