If Summer made a sacrifice and has something to do with Cinder, I'm pretty sure the sacrifice was faking her own death and recruiting Cinder so that she could work from the shadows, having Cinder do a lot of the work for her.

Not somehow possessing Cinder's body.

I think "All your faith in ancient ways leaves you trapped inside a maze" refers to the kingdoms, especially their governments, still doing things with the ancient methods, which are incredibly outdated.
