Just as an initial reaction, the opening paragraphs are a little hard to get through. For one, the grammar is a little off and for two, the MC comes off a bit whiny. I mean, it's understandable, she is dying, but that doesn't keep her from sounding a little annoying.
In the first episode, the narrative is a little repetitive with the narrator saying the phrase "returned (or returning) to me" three times in succession and starting a series of sentences with "My."
And have to a agree with @Kelheor, she's a little creepy and I'm hoping (and assuming) this is brought up and addressed later. And it was a little confusing, since it seemed as though the perspectives were switched between Cherilyn and the girl who was summoned into the world. I thought it was the same person speaking, but I guess not?
