For the genre you're seeking, I think your story will work very well. I've read (and loved) Frank Peretti and Ted Dekker and they are edgy in that genre with violence (and great suspense) in their books.
I just moved to South Dakota from Puyallup. I drove by the mission in October on my way.
That looks like a great spot to live - in the summer.
Take care!!

Oh my gosh. Someone actually lives in Cataldo?? I always check it out when I drive by the mission - but have never stopped to sight see.
God bless!!
