I like the idea, but the dialogue is a bit stiff and it feels like you're stuffing just a bit too much info in.
Ever read "Hawke's Harbor" by S.E. Hinton?

Lots of spelling mistakes- and I'm really confused as to a lot of things. Why did he call her nightchild? Had she always only been able to see in the dark? And why would he trap her in a coffin of spiders or how did he come about to torture her for two straight years- how did he capture her? I hope that you further the story with a little more history otherwise the readers will be blind to what HAS happened- and you need the has just as much as what IS happening.
