1. Almost to Die For:
On her sixteenth birthday, Anastasija Parker learns that her so-called deadbeat dad is actually a vampire king. And he wants Ana to assume her rightful position at his side, in spite of the fact that she has witch's blood running through her veins - from her mother's side.
Too bad witches and vampires are mortal enemies. And now Ana's parents are at each other's throats over her future. It's up to Ana to make a choice, but deciding your eternal destiny is a pretty big deal for a girl who just wants to get through high school.

2. Almost Final Curtain:
Craving the spotlight is in her blood.
Ever since high school student Anastasija Parker discovered she was vampire royalty, her life has been sort of crazy. The half-vampire- half-witch just wants some normalcy, and trying out for the spring musical seems like the perfect fix.
But when the ancient talisman that stands between vampire freedom and slavery to witches is stolen, Ana has to skip rehersal and track down the dangerous artifact before someone uses it to make this year's curtain call her last...

3. Almost Everything:
Whoever said vacations were relaxing?
To say half-vampire, half-witch Ana Parker has boy trouble is putting it lightly—something her text messaging bill can attest to. Her rocker ex-boyfriend Nikolai is trying to heat things up again, and high school hockey star Mathew wants her to try out with him for the Renaissance Festival. At least her sort-of boyfriend Elias isn’t hounding her cell—considering the vampire knight is currently living in her basement.
Ever since her father banished Elias and Ana from the court of the Northern vampires, Ana has been trying to live a normal life. But when the Prince of the Southern Region vampires informs Ana that they’re on the brink of war and she accidentally offers up Elias as a peace offering, the princess knows that she’s going to need some help to get out of the situation.
