Ex-Marine MacArthur Patton made millions on top-secret, black-ops jobs.

Now, he's tackling his most dangerous mission ever—marriage.

Well, fake marriage anyway.

To keep weapons out of the hands of terrorists, Mac needs a fiancée.

A sweet, demure, compliant fiancée.

A woman to serve as arm candy while Mac completes a covert arms deal.

His sister claims she knows just the woman to join him in Mexico.

She's sending her best friend to play Mac's fake fiancée.

"Sweet" and "compliant" aren't in Kelli Landers's repertoire.

A badass veterinarian who's not afraid to neuter...well, anyone,

Kelli can't wait to bring Mr. Tall-Dark-and-Detached to his knees.

Her crush on the commitment-phobe only sweetens her scheme to seduce him.

Love isn't part of the plan.

But the deeper they fall into their ruse, the more dangerous the mission becomes.

Pretty soon, Mac and Kelli have more than their hearts on the line.
