Dark of Night

Dark of Night is an action/adventure with a touch of romance thrown in for good measure.
Meet Antonia "Toni" Andiamo, part-time Mafia assassin, part-time mercenary. She's the founder and owner of an elite security firm that often takes on work the government agencies won't touch. Her uncle and head of the Metro-Detroit Mafioso, Don Antonio "Big Tony" Andiamo, gives her an assignment working off-the-books. The FBI needs her covert skills to stop a suspected terrorist plot.
When her recent one-night-stand turns out to be her FBI liaison, things get more than interesting.
Despite Toni's innate mistrust of any government agency, she takes the assignment ultimately finding herself, her family, and her country in greater danger than she'd ever thought possible.
