I liked this better than book #1 because the guys treated Jess better and didn't try to freak her out of her mind like Desi's guys did in book #1. But, hmmm...Finn felt like a copy of Will from book #1 -- quiet, shy, submissive, unsure --so it felt like the author was writing the same character all over again. Dov was floundering and is manifestly not an alpha type. It's very hard to admire someone who is so lacking in self-confidence. Elijah is definitely an alpha type; he's a take-charge, "I know what to do" sort, almost a bit brash. I didn't like the brashness... so unfortunately, I didn't connect with any of the guys at all.
As for Jess, hmmm I don't know. I also didn't feel that I knew her personality very well. She is supposed to be this firecracker that we saw in book #1, but in this book she's also uncertain, questioning herself, not feeling like she belongs. In fact, she gets into trouble because of that fear -- that she doesn't belong. She's hurt by something Elijah said, storms out, and you know in a book that's never a good sign because it makes you vulnerable to enemy attack. Just sayin'. I thought her reactions felt genuine and it made sense to question things, but I had expected her to be this reckless badass heroine, which she just wasn't.
We find out more about Concept lore and how they have a tendency to form packs. A lot of different... umm... concepts are introduced. As in ideas, not monsters. Concepts like 'Vessel' and 'Slate'. I'd have wanted to know how the enemy knew who's a Vessel and who's a Slate. Is there a way to tell? Tracing ancestry and DNA? Or what? How is it that the enemy could know so much, while even strong and old Concepts like Penn from book #1 didn't know?
The showdown felt a bit anti-climactic -- like, everyone was so afraid of the bad guy, but in the end he seemed so easy to defeat. The way that Jess got integrated into the pack at the end felt... too convenient.
This story was just missing something for me. The relationships didn't feel strong or real. In book #1, Penn, JD and Will have been together for years, so they already had established bonds and they loved each other. We could see this in their interactions and the way they knew each other and responded to each other. In this book, none of them really know each other, so the author had to pull them together. Elijah and Dov met a year ago, very briefly, and have had no contact ever since. Elijah has strong feelings for Dov, but it's based on a single fleeting kiss, which feels very flimsy to me. (Sounds like a fairy tale, right? Sleeping Beauty?)
Dov has known Jess longer than he's known Elijah, in terms of time spent with her. But it's still a very short time, just a week. And the circumstances have been weird. They met when Dov was working for a bad guy and had kidnapped Jess under orders from his 'host' (or boss). At the end of book #1, Dov's host was vanquished, so had nowhere to go. For some reason, Jess decided to take him in and let him share her living space... even though he had kidnapped her and put her in harm's way by bringing her to his boss! So they're living together, but it's awkward, because they don't know each other at all. It turns out that now that Dov is free to follow his conscience, he's not a bad guy after all. Which, you know, does make things interesting, but I needed to see a lot more interaction and connection between him and Jess to make it believable that they were falling for each other. I wished the author had shown us more of what happened between them as they lived together and got to know each other.
Then we get Finn who is pansexual, which isn't an issue, but it just seems that his connection to Dov, Jess, and Elijah is mostly based on sexual attraction than anything else. They don't know him as a person and I didn't see them getting to know him as a person, nor he they. Elijah seems more focused on Dov than on anyone else, and almost seems to sideline Jess at times. By the end of the book, I did not really believe that they all were in love with each other, and for a romance, that means it wasn't a very successful story.
