It wasn't the best book ever. It was better than the last book I read by this author, which was also the first book I'd read by this author. I talked about starting that book in this post, and it did indeed begin very promisingly, but then it all went horribly, mushily, disappointingly wrong. The character, who was flat and without agency at the beginning of the book for understandable reasons, continued to be flat and insipid for way too long, and the big reveal about the Big Terrifying Menace was more of a splat than a fireworks explosion.

The writing and characterization don't quite rise above 'good' to 'really good'. A couple of times I wondered if I was just missing things. Daniel uses the word "amazing" to describe Kayla way too many times, but then at one point he said "you are..." and she says " Yes, yes, amazing, I know", so maybe the author meant to do that, but it doesn't do much to make him seem like more than a vocabulary-limited dolt. At one point when Kayla discovers that he's lied to her about something, instead of flipping out about it she says that she actually sees why he lied about it and thinks it was a reasonable decision - I LOVED this, since one of my pet peeves is when people go ballistic over being lied to when, if they thought about it for a second, they probably would have lied similarly in the same situation.
But anything I admired was only on a cerebral level - I didn't really feel any of it. This might be just due to my mental and emotional state right now, but I don't think all of it was. This is an author who has a knack for plotting; if she ever steps up her writing game, she might be amazing.
Memorable quotes:
-"'You know, if you worked for me and you made me wait that long, I'd have flogged you.' Kayla hopped into the car and buckled her seat belt. 'No, you wouldn't. You have people to flog your people.' 'Yes, yes I do. I have floggers.' 'And slappers, for anyone who doesn't deserve a full-out flogging.'"
-"Kayla had felt as if she were a pillow, battered and damp. She'd slept badly, racked with guilt, and she'd woken to an empty house... After that, Kayla had started to feel angry. And the anger ate the guilt for goddamn breakfast."
-"'Of course it's not over. Don't you know how these things work? The wise old woman gave you cryptic advice to start you on your quest. Now the trusty sidekick, who is far smarter than the heroine, finds the pertinent information our beloved lead needs. Or she at least checks Wikipedia.'"
-"She wanted to fall into that smile. It made her want to frolic through fields with him, and Kayla had never frolicked through a field in her life. Oh, good grief, am I falling for him? How completely prosaic."
-"'This is serious. You have the common sense of a dim-witted lemming, and I don't want you to plunge off a cliff and die.' A corner of his lips quirked up. 'Hey, you do care.'"
-"'Don't listen to her. This is your destiny. This is what we've worked so long and so hard for. This is our chance at greatness! Every great achievement requires a great sacrifice.' 'What fortune cookie did you read that in?' Kayla asked.
