Rose Hathaway is coming from near the end of Last Sacrifice (right before the gunshot). For those who don't know the series, Rose is a dhampir (half vampire, half human) who was raised to protect moroi (the good vampires). She protects one in particular, Lissa Dragomr. She's a badass fighter, sarcastic and tends to be irresponsible (though she's getting better!)
Allison Argent from Teen Wolf is coming from just after she died. I don't know the rules here on that one... will she need to be healed upon arrival or do she arrive healed? She is a werewolf hunter who is wicked with a crossbow.
Faye Chamberlain from The Secret Circle. She's coming from after book 3 The Power. She is co-leader of the coven along with Cassie and Diana. She doesn't believe in just light magic or just dark magic, she believes that they can both be used to suit whatever need. She has no qualms about using either. She can be a bitch of a bitch and is very outspoken, but ultimately she does mean well.
These three are joining Emma Carstairs and Annabeth Chase. All five of my girls are open for plot.
So far that's all I have planned, but I will undoubtedly be enabled into more.
