Just to be safe, I've marked this post with a spoiler tag.
I like where the train of events is going. A simple fetch that could have been completed by an experienced hunter living in The Feral Zone, but now Lane has to take things into her own hands. And boy DOES she take things into her own hands. That girl's a strong one, I tell you what.
At mid-point in this book, I'm more than happy about how things are progressing. Lane doesn't strike me as a heroine who stands out any more than others have in other YA dystopians, but she's agreeable and I like her. It took me a while to warm up to her, but not because I disliked her or anything, only really because I didn't have any outstanding thoughts about her at all. But all of her little quirks and mannerisms, her do-gooder personality, her stubborn pride, and the fact that she knows when she needs to fall back rather than stubbornly charge forward... it makes for a more likable character than you'd usually get to see in those termed "Too Stupid To Live" types who are always out to prove something.
So I applaud her.
As for Rafe (yes, we've moved on from Everson, apparently, who actually went from agreeable to, "dear god, just go away" all too quickly), I like him too. I was conflicted, cause the guy's a bit of an ass, and I'm more or less for the good boy, most of the time. But Rafe is a snarky ass, and before I knew it, he picked up my heart and sang to it. I'm not saying that I'm in love with him or anything, but he's got my attention. He's rude and a jerk when it suits him, but you can tell he's not a complete selfish prick.
It works. These guys are all fairly natural and realistic... well, as realistic as you can expect in a post-apocalyptic dystopian.
So, yes, I'm quite enjoying this book.
I'm also formulating a possible guess at what the series is veering into and it's got me quite excited, actually. I've got ideas, and I hope that the author's got the same ideas, if the hints at the beginning of the book are any indication. So this might be a series that I'm going to latch onto.
