So this is the second of the library books I recently got out. I picked it up on a whim, and I'm still not entirely sure what I think it about it, so hopefully writing my thoughts down will help me make it clear in my head. 
 Glow is the story of two teenagers, Waverly and Kieran on spaceship heading towards New Earth. It's been travelling for 42 years, and has a twin ship a year ahead of them. Or, it was supposed to be, until they come across the ship in the nebula and basically all hell ensues. 
 I enjoyed the plot of the story. I don't read much sci-fi stuff set in space, and I really wasn't that enamoured with the last one I read (Across the Universe by Beth Revis). However, I thought the plot was well crafted and written. The action starts basically from the very first page, and we jump right into the story, which I loved about it. 
 However, my main problems was with the characters. Waverly and Kieran are a couple, but are separated from very early on. I don't usually like couples that are together before the novel starts, because then I don't feel very invested in their relationship, and I kind of felt that way with the two of them, possibly because Waverly herself was somewhat unsure about the relationship. The first couple of pages set up their relationship, and was sweet until Kieran got all creepy and proposed marriage to her (she is 15 and he is 16 and I don't care that the culture is different on the ship, it's entirely weird for people that young to get married and I'm glad that Waverly wasn't sure about it). 
 The book was written in third person narration and split in to parts, with it alternating on focusing on Kieran, and then Waverly. I like Waverly's side of the story; I thought she was a smart and resourceful heroine, who didn't pine after Kieran too much and stayed focused on her goal. I don't really like reading characters that young, but she definitely acted older than her 15 years, which is probably why I didn't mind it that much. I thought she did some really brave things, and so I quite admired her. 
 Kieran and his side of the story, on the other hand, irritated me from the very beginning. Trapped with Kieran is Seth, another sort-of love interest for Waverly (God, I hate love triangles), and so there is competition between them from the word 'go', and the aggression and competition was too much for me. I started off disliking Seth; I thought he was rude to Kieran for no reason. Kieran has to take over command of the ship, and Seth starts a sort of rebellion against him. There was a moment when it seemed like Seth and Kieran could work together, but Seth has issues and so overthrew Kieran. 
 Seth and Kieran are, I believe, supposed to be set up like opposites. Kieran is everyone's favourite, while Seth is moody and sullen. And that did sort of shine through. However, I didn't like either of them at all, and think that Waverly would be better off without either of them. Seth is violent and rude and tells lies about Kieran; Kieran gets all religious at the end, paralleling the bad guy in the novel, and also talks often about how Waverly 'needs' him. Not only is the pining annoying, but Waverly was quite capable of saving herself and others. 
 I don't have anything against religion, though I would call myself an atheist, but Kieran's religion at the end too much reflects what went wrong on the other ship, and it was too domineering. 
 Basically, I understand that the author needed to show us what was happening on both ships, but I would have preferred if everything was narrated by Waverly's point of view. I just couldn't stand Kieran or Seth, and spent the entirety of their section wishing I was with Waverly. I also felt that at the beginning, the sense of dramatic irony was too strong. I knew exactly what had happened on the other ship, and the fact that Waverly didn't was irritating to me; it took her awhile to be fully convinced that the bad guy was in fact the bad guy. 
 The plot was strong and it was well-written, and it could have been very good if I'd liked Kieran or Seth.
