Darkest Hour

Royce Devereaux isn't your average sexy professor. He has a lot of rules in his professional and personal life. He keeps both worlds separated. He has to. He's somewhat of a public figure-and yes, he's made enemies climbing to the top. Being a world-famous paleontology professor doesn't mix well with his romantic life.

It's only one semester. Right?
But when an enemy decides to use Kenzie to force his hand, Royce has no choice but to keep her close. Very, very close. His two worlds have just collided. He just hopes he can let her go once the danger is over…
