Married to the Operative by Ashley Zakrzewski

What happens when you receive orders from the NSA to marry a complete stranger?
Maxwell, a highly decorated member of the NSA’s task force, stared at the orders in front of him without bothering to disguise his skepticism.
The mission, to marry Vanessa Lambert, who was worth several billions of dollars, received two Ph.D.’s before the age of twenty-one, and the foremost authority on biological agents and neural mapping.
On paper, she is remarkable, but nowhere did it mention training to be an operative.
A fake marriage, an untrained partner, and no expectation of gaining feelings… what could go wrong?
