Story Starting Problems

Hello, Gymnast2801 here!
Okay, I really need help, like badly. Let me explain...

My story Death Awaits is about a shapeshifter named Para (that's her nickname), a girl who can see monsters and the mythical world named Sadie, and a child who can just now see monsters named Brianna. Sadie is voulonteering at the same summer camp Brianna goes to and she has to rescue Brianna from the grasp of these monsters along with the shapeshifter Para (she can't shift into human form).

I'm not quite sure what a good camp would be to start all this at and I'm also not sure how to even start this story (it is from Para's pov) so I really need help!!

I also just had the idea that Sadie could volunteer at a daycare that Brianna goes to!

How about starting with Brianna's kidnapping?

Yeah, I think you should start with Brianna. From her perspective, you can introduce the conflict and all.
