Unordinary

My name is Zelda. 'Z' for short. Me and my twin sister,Corliss, and our two kid friends, Hazel and Griffith, are all a part of a secret supernatural spy organization, and no one can find out about us. I'm not sure why yet, but I'll figure that out later. But one day, our boss calls our homestead and tells us that two guys know about us, and they are planning an attack on all of us. While on our second mission, Corliss, goes missing while we are chasing down the two guys boss. I know something is wrong, I can feel it in my gut. But what exactly WAS wrong? I just knew we had to find her, and I just knew the worst would end up with her if we didn't find her in time. P.s. there is some profane language is used!
