Lethal Kiss by Taylor Grothe

Something ravenous lurks below the marble floors of Preston University...

Marcella might be a monster, but she's careful. After getting hired at Preston University, she intends to lay low and keep her meals discreet.

Trapped in the rat race of academia, all Lacie wants is to make tenure. This will be her year, and nothing is going to stand in her way.

That is, until bodies start dropping.Marcella swears it isn't her doing--as if she'd be that sloppy. Whatever's killing their coworkers is older, and far less restrained. Lacie doesn't know who to trust, but better the monster you know...

The deeper they dig, the more they're drawn to each other... and the more something else is drawn to them.

After all, desire has teeth of its own.
