I must admit, I'm having a bit of trouble putting thoughts into words at the moment. Forgive me if none of this makes any sense. Also, I just caught up on a big chunk of SoW at once, and the chapter lines are blurred in my mind, and I haven't bothered to look at the old feedback threads, so forgive me if I cover ground that's been beaten fallow in past threads.
First, I think Kajsa is a great character. She doesn't often make sense, but I think that's to be expected. I will say, however, that Kail looks awfully shallow in these chapters. I can see no motivation for him to want to get in so deep with this woman he only just met, beyond her hotness. I mean, she had just tried to kill him. How does that spur him to kiss and bed her? Does not compute.
He then looks crass and selfish when he realizes he just had unprotected sex and worries a bit about STD's without giving a second thought to the most common of sexually transmitted diseases: conception.
Has he given any thought to where his relationship with Kajsa will lead? Does he plan to stay in the world forever? Does he care at all that Ellie will probably freak (or at least be devastated) when she finds out? We've seen no such thoughts even cross his mind, which, again, makes him look more than a little foolish, and makes him less sympathetic to me.
This may match your intent for his character perfectly, and that may be okay, as long as you're aware that that's what you're doing.
Then there's Ellie, and again, I have to wonder what she's thinking. There's just no way, at least in my mind, that she could really believe that Kail will still be alive when she gets back to him. How long has she left him lying with a bullet hole in his chest? Why is it that she doesn't think to ask the wolves to carry him? Why doesn't she think to do it herself upon discovering her magically enhanced strength? Why doesn't she ask Bloodbath where to find help, instead of simply ignoring his warning that the village is not inhabited by nice people?
What's more, how does Bloodbath just let her walk into such a dangerous situation? He tells her that he can't protect her from them, but apparently his oath to protect her doesn't extend to protecting her from herself.
I like your world, though I'm still confused by it. It seems that every world knows about the multiplicity of worlds and reality of magic except ours, which doesn't make sense to me. I don't want this world to be Kail's final destination; I either want to see more worlds, or for him to return and discover an undercurrent of magic in our own.
And I think my brain just ran out of juice. I wanted to say more, but I can't remember about what, so I'll just close by saying I'm still interested to see where this goes, provided it *does* go somewhere.
