I really wanted to give this book 5 stars. I really did.
It was incredible from the beginning: captivating, evocative, thrilling, mysterious..it only had one flaw in my opinion, and I hoped this flaw wouldn't affect the ending, but it did.
The flaw was Jeb. I didn't like him from the start, and things didn't improve along the book; it got even worse, actually. I found him to be a very flat and clichèd character: his defining trait seemed to be his undying love for Alyssa. The author tried to trow in some troubled family history, to give him some depth I suppose, but it didn't work. Maybe it's because we don't get to see what's going inside his head, but to me he always felt like a piece of cardboard next to the complex and very much alive Alyssa. Even Morpheus, the classic mysterious "bad" guy, turned out to be more enjoyable than Jeb, and in fact I rooted for him thourough the story.
So, the ending obviously let me down. Actually, I would've preferred an open ending, with Alyssa trying to adjust to her life before rushing to get a boyfriend.
I also think Morpehus would've been a better match for her because he really knows her, and Alyssa doesn't have to constantly remind him or show him that she's an independent being capable to make her own decision.
Anyway, the book was really really good, and I recommend it; maybe you won't have the same opinion as mine on Jeb, who knows :)
