I enjoyed this book. 
 Greek mythology serves as a lot of exposition, but the story itself doesn't read like a myth. I wasn't crazy about that aspect. I love Greek Mythology, I was kind of hoping to see a little bit more than just English class lectures that conveniently fit what the characters are going through. Aren't English classes awesome? It's like the syllabus is synced up with personal tragedy. 
 The entire plot of this book is based on the decisions of a sixteen year old girl when she was having a really bad day. Oh god. It's as much of a shit-storm as you'd expect. Once you get past the fact she was being an idiot, this book is good. 
 I kind of wondered why Cole got the shaft as the love interest. I mean, he serves as Hades, doesn't he? Persephone, at least in the adaptations I've read, comes around eventually. A little bit. Maybe. Kind of? 
 Probably not, but call me a hopeless romantic. But I liked Cole. He clearly loved Nikki, and while he wasn't happy about it, he did his best to make her happy in the ways he knew how to. She did go to him. He was very persuasive, but he didn't force her. He had those asshole Jacob black-esque moments in the love triangle where I wanted to shove his head in an oven. Other than that, I still like him. 
 I want to say I hated the "Be all and end all" of Nikki and Jack's relationship, but...Who am I kidding? I cried. Yeah. Not proud of it either. This 100 books of 2013 has not been very good for me. Mostly I just read about people getting way more action than me and start crying "Nobody's going to love me like that!" when boys dive into hell to save their girlfriends. Very unsettling. 
 Back to the point, their relationship was very romantic, but slow paced. And there's that goddamn "girl walks into the room at the wrong time and misunderstands EVERYTHING" plotpoint. God I hate that. So she thinks for half the book he cheated on her; he didn't, and because of the misunderstanding she chooses to go with Cole to the underworld where she won't have to feel and will forget everything. So basically every bad thing happened because of her insecurity and distrust of the boy she sees as the love of her life. Everything could have been resolved with good communication skills. I hate when people can use their words but choose not to. There's also the, "I think you've moved on and are with another girl now" aspect with the girl's best friend, Jules, which.... Oh my god. Just say you're not dating. Just talk. I was waiting for a scene where she checks Facebook 80 times to see if their relationship status changed. TALK. TO HIM. The plot is the lead character lying a lot about having to return to the underworld and still being in love with Jack. This is why honesty is so important to me. Because lying to protect the people you love is actually cliche now. Holy crap. 
 Also, again with the abstinence? Really? Really? Why do authors think teenagers are sexless and have absolutely no urges? We do. Trust me, we do. I's just...not even talked bout in this book. There's one instance were they almost talk about sex, but it's never addressed again. I understand that Nikki didn't feel ready, but when is ready? Genuine question. I would have liked to know where the author is going with this. If you're going to preach, have the balls to preach. Don't elude to your message. Say it. 
 This book flew by for me, I enjoyed the boys, the character voice. Good pacing. None of the side characters particularly stood out, except maybe Will, I enjoyed him. Jack was the best developed, but Cole showed great potential. Excited to read the next installment.
