She's looking forward to a normal summer with her husband and step son when an old enemy from the past appears--the vampire Chael--and what he reveals changes everything.

Life becomes even more complicated when her business partner, David, and their boss become victims of a Ponzy scheme. But it's more than money at stake. Someone is killing off the investors one by one. It's up to Anna and David to find out who before their boss becomes the next victim.
