nanowrimo_lj | my intro and ideas

Hi all,

I tried NaNoWriMo for the first time a year ago, and while I didn't win, felt I made a genuinely respectable showing -- 10K words. Not so bad for someone working a full time job and trying to care for a human and feline family. :)

Anyway, I'm giving serious thought to giving it another go, and was looking at three of the four ideas I was trying to choose from last time. Here they are:

Neith Imports (dark fantasy/suspense)
In a world where vampires run nations, a secret society of spies and vampire hunters works to bring down the monsters -- even at the price of becoming monsters themselves.
The Nanking Sword (dark fantasy/historical)
An man inherits a samurai sword and immediately begins suffering from horrifying dreams and visions. He realizes he must find out the truth about the sword, and return it to its original owners, for justice to be served.
Elixir Sulfanilamide (historical with fantasy elements)
In the autumn of 1937, agents of the FDA must locate every last drop of a tainted drug. One of them is a woman with very special mental gifts. Can she use them to track down the deadly medicine that is causing children to die?

Your feedback, either in terms of "best idea for a novel" or "best idea for a novel that I have a hope in heck of writing in one month's time" -- or any other thoughts you might have on these ideas -- is very welcome.
