Sounds like the plot for a paranormal... Do you get the feeling that we're reaching a bit far? If one vampire is good, then let's have two or three. If werewolves and weretigers are fabulous, why not weresheep and wererabbits?
Now books with demons, angels, every type of shifter, faeries, elves, gnomes, dragons, witches are the norm rather than the twist. Actually, in more than one book I've read, the human character is the weird one. When did we turn into the bad guys? Why are we no longer the desirable love interest? Why are we not good enough for the hero or heroine unless we have a special talent?
In our rush for the ever more exotic character, ordinary men and women are discarded, thrust aside and left behind except for those instances when we need a villain. Then--then we're good enough. It strikes me as odd that we are powerful enough to be villains when our original position was just the opposite.
In the early days of paranormal the weres and vamps were the bad guys with the humans triumphing over them after overcoming huge obstacles. Now the roles are reversed. Interesting.
Where will we go from here?
