He’s a spy for the Clandestine Services Agency. She’s a spy for the CIA. They’ve been clashing on joint missions for months, but their worlds are about to seriously collide.

Here are three things that I know. 1) I’m an expert at reading body language, 2) I excel as an intelligence operative, and 3) Ledger Lancaster — daring, fearless, and recklessly charming — is my rival. Or enemy, depending on the day.

What I didn’t realize from our first mission overlap a year and a half ago — a mission I thought Ledger was using to gain the upper hand only for me to beat him at his own game — was that his interest in me wasn’t an act. How could I have guessed?

Since then, Ledger and I have been enjoying (me more so than he) our fierce competitive rivalry, all while I pretend I don’t have abandonment issues. But everything changes when our agencies have a mission overlap, and we are sent on an operation spanning European countries. As in working together, not working against.

This is not our usual playbook.

Now, while spending every hour of the day together, Ledger keeps reminding me of all the reasons to fall for him — if I was the kind of girl to fall in love. And if I’m as good at reading body language as I think I am, Ledger isn’t faking his feelings for me this time, either, and these sparks between us feel dangerously real.

Am I falling for my biggest rival? It seems so. Somebody send an extraction team ASAP.

“Spies Don’t Fall for Their Rival” is a closed-door romantic comedy brimming with chemistry, sizzling tension, and witty banter. In a world where the family business is the spy business, prepare to laugh, swoon, and fall head over heels in love.
