I have a few ideas... OnexOne, Kumos pack, Brawl, werewolves, and Vampires.

With Brawl, its all the characters living in one house. (I'm evil ^W^) The werwolf one is a tad more complicated... The Kumos Pack is listed under Midnight Run and the Vampire one is listed under Prayer for the Refugee (Vampire's Reign). Suggestions...?

I can post the plots here if you'd like to read.

EDIT:

Kumos Clan Plot: There is a pack hidden in Riverside Valley. The pack is known as Lost, for the lost tribes. Its a pack of Kumos, all species live in it. Somehow, one by one, they are being picked off and found days later as tamed pets.

The pack is desperate to keep more of their own becoming tamed beasts and set off for another place to stay, away from other life. Will their trip take them to paradise? Or to their doom?

Vampire Plot: The vampire kingdoms have slowly dominated Earth. There are a few rebels against the vampires, including humans, vampires, lycans etc. Sadly, most of those rebels are shot down when they attack. Few have lived to tell the tale, and have suffered serious injuries. A destroyed town that not even the vampire nobles, who rule, dare send their men is where the rebels stay.

Werewolf: A pack leader falls in love with the daughter of the enemy leader's clan. He either steals her away or kills her clan to have her. He finds out she has a weak heart and can't take too much strain. He has to put up with her attitude and pushing him away while she has to deal with his affections thrown at her.

The werewolf one isn't very detailed.... xP
