Daimon follows Alex in the events before and a bit after her mother's dead. We can see how they live in Miami, hidden among humans.
Alex was still kickass in this prequel eventhough she hasn't had training in three years. The boy she was dating (just like her mother I can't remember his name >_<) was such a wuss, dude! When two other guys were bothering Alex and her little boyfriend, Alex kicked their butts and what does he do? He breaks us with her. Good riddance, Alex! She was still even thinking about her longago crush Aiden St. Delphi anyway.
When Alex finds her mother's lifeless body in her house things get bad for her. She runs from the house after killing a daimon and tries to find her way to the Covenant. Of course we all know (anyone who has read Half-Blood) that things don't go that well.
I didn't think this was as good Half-Blood but it was likable for a prequel short story.
