The Offering

What do you get when you cross Sydney Bristow of Alias with Buffy the Vampire Slayer?  Carla Deville.

            She's a kick-ass CIA operative, who relies on the power of logic and reason to always get her man. But now she's up against the Illuminati, a shadowy occult organization that has abducted her sister and plans to launch a nuclear terrorist attack.

            To make matters worse, Mark Lyons, the arrogant rich boy she once loved and lost keeps turning up in the wrong places.  Can she believe him when he claims to still love her, or is he simply carrying out some part of the Illuminati's evil plan?
