Undercover Soldier (Harlequin Romantic Suspense Series #1714) Book

Computer tech—and expert hacker—Sherra Alexander doesn't give up easily. Yet her dig into military records has placed her under federal scrutiny. In too deep, she knows anything can happen. What she doesn't anticipate is finding her presumed-dead ex-lover, army lieutenant Brody McAndrews, alive and in her apartment.

On a covert mission to uncover the truth behind a suspicious explosion that killed a comrade with a similar name, Brody must stop Sherra's research—and protect her. The only way to do that is to keep her extremely close, whether she likes it or not. As a battle of wills brings on the passion in full force, an unknown threat zeroes in, determined to silence them both—permanently.
