No kiss goes unpunished.

The woman known as Ace...

Rhea, a former Coast Guard pilot, is on the search for work after being fired. Hoping to hide from her troubles, Rhea recklessly kisses a sexy stranger at a wedding before finding herself desperate enough to enter a dangerous contract with security firm AMN. But the first day on a job can be awkward, especially when your anonymous kisser is your new team leader...

The one they call Viking...

Reginn is weighed down by the blood on his hands. Unable to leave his mistakes in the past, Reginn won't take a chance on a hotshot pilot without combat experience. He doesn't believe Rhea has what it takes to complete the mission, and he makes sure she knows it. Despite his objections, Rhea is their last chance—and he can't deny the woman kisses as good as she spars.

When south of the equator, throw the rule book out the window because the heat is rising and so are the secrets.

Can Reginn and Rhea save each other, or will their desire lead to a darkness neither can return from?
