Call Sign: Thunder by Livia Grant

He’d already killed to keep her safe, but what does he do when he’s the one hurting her?

Zach
Flying choppers was what Zachary ‘Thunder’ Garrett lived for, but when he’s shot down over cartel country, he’ll have to decide between completing his mission and trying to save an innocent American woman. His elite team had been sent in to retrieve dangerous weapons and deadly drugs, not kidnapped tourists. But ruthless drug lords were hurting her — bad — and he won’t leave her behind, even if it gets him court martialed or worse — dead.

Allie
She’s waited her whole life to escape the limelight of being a powerful US Senator’s only daughter. Spending a semester as an exchange student in Colombia was her big chance to let her hair down, away from her overprotective father and prying cameras. But when she’s stolen off the streets of Bogata in broad daylight, she realizes just how dangerous the world could be. The only thing standing between her and continued torture is a lone warrior — her hero.
Surviving life and death danger may have brought them close, but the realities of their different worlds was determined to keep them apart. Could an undercover job opportunity with an elite team of mercenaries be the answer to all of their problems?
