In a small town called Sour Lake, a 14 year old girl named Lisa is just starting her freshman year at Hardin-Jefferson High School. She is so excited until she gets there and finds that a mysterious, new guy is staring at her. At the end of the day her life doesn't seem the same. She has to figure out what's going on. But she soon going to find out that the only person that could help her is the new guy that came to town that year.

Annelise lives a normal, slightly hectic life like any other college student does. There's only one difference : she's an Assassin by night. (cliche, yes yes, but you gotta read it cause it's bit different.) The thing is, she doesn't kill the people she's assigned to get. She lives as peacefully as anyone with a double life does. That is, until someone in the assassin's network starts giving out many assssin's real names and, for some, it starts showing their pictures. Fingers start pointing at her, and the rest is history.
