While drinking cosmopolitans in a fabulous little black dress, Gwendolyn Kidd meets the man of her dreams. Then she takes him home. Then she wakes up alone. But her fear that she lost her dream man turns into a relationship with a mystery man when, night after night in the dead of night, he comes back for more. Hoping it will blossom into something real, she lets him.

But she doesn't even know his name.

Gwen's struggling with the decision to end their crazy non-relationship when her sister-from-hell, Ginger's best friend pays a visit and warns Gwen that if she and her sister don't get smart, they'll both get d-e-a-d, dead.

Gwen has no clue what's going on, but she's used to Ginger's antics and decides to lay the problem on her sister's biker boyfriend's doorstep. Bad choice. She catches the eye of the biker hottie president of the Chaos Motorcycle Club. Not long after she gets the attention of a Denver police detective who surely is on the cover of the DPD's Hot Guy calendar. And lastly she hits the Denver Underground radar with a big, loud ping.

This means Gwen's Mystery Man, Cabe "Hawk" Delgado has to step in to keep her safe. But when Hawk gets a dose of Gwen in the daylight, he makes the decision that he finally wants real with Gwen.

However, when Gwen gets a dose of badass, bossy, straight-talker Hawk in the daylight, she decides she's done.

Thus begins the head to head of Commando vs. Cosmo Girl as Hawk woos Gwen in his unique way, and Gwen survives firebombs, drive-bys, kidnappings, hot pursuits by biker hotties and gorgeous police detectives and discovers the heartbreaking reason why Hawk kept her at arm's length.

And as all this happens, Gwen finds that her sister's troubles are serious trouble and she must decide who to keep alive: her sister-from-hell or the man of her dreams.
