Can someone explain the plot simply? I’m confused

This is completely based on what I've read

Basically the current queen wants to eradicate Beast and other species that aren't completely human so our FL comes into play because she has the exact same or similar power that the queen has and that's why Reynold was searching for her to figure out what it is so they can stop the queen and Reynold the wants to build a place where everybody could live peacefully together so they need the fl's help identifying the objects that the queen has " blessed"
