I don't know what to do with this book. Well, read it, obviously. But how to describe it in a way that makes sense? Short description first, I guess. This is a brand of YA wish fulfillment in the sense that the background of the characters, and their prospects going forward, are unique and interesting. In this case, both Luke and Vada are heavily into music and each are incredibly talented in their own ways, and, more importantly, have recognition for those talents. Even more fantastic (in the fantasy sense) is that each knows pretty much what they want to do with those talents and are lining up their (likely successful) efforts for their chosen paths.
And Hahn does an outstanding job taking that basis and breathing life into it. Both Vada and Luke feel fully-realized, with family trauma that mirrors and reflects each others' in a way that draws a great spectrum of possibility out for illustration. They each struggle for support and love, even though both have, at heart, nurturing families. And I loved how they found each other and became friends and came to support and understand one another. Particularly engaging was the role that an in-depth knowledge and shared love of music played in their communication. This might have crashed hard, but I think Hahn does a pretty good job giving lots of detail, but never so much that the story bogs down or that you get the feeling you are being judged for not getting all the references they toss back and forth to one another. On reflection, this is quite an achievement, I think, because it was so central and that would have been an easy overbalance to make.
Anyway, the plot moves smoothly, though a bit predictably. I loved being along for the ride, though, so that's not actually a bad thing. I'm not a fan of the over-drama that happens in the final stretch that serves as a dark moment for the two leads. And that isn't mitigated by having the one over-reacting knowing (and acknowledging internally) that they are overreacting and knowing that they'll get over it and patch things up, just . . . not yet. I kind of liked that the grand gesture wasn't what patched them up, and that was good. Though offsetting that a bit is that I didn't buy the grand gesture as depicted (too successful, too big, too out-of-character).
Anyway, this is a great YA romance with a specific flavor (music) that is engaging in a way that invites the reader to participate in the love of something that may be new. I found that refreshing. The drawbacks were enough to drop this to four stars, but it was a lovely read.
A note about Faith: One interesting sub-aspect of the story was Christian Faith being treated with actual respect. It isn't central, but Vada's mother and best friend are believers and their faith is shown as a strength in their lives and a support in trial. Further, Vada's participation is more than rote and even progresses towards a deeper belief, though without any definitive steps or resolve. This was an interesting dynamic and, like the love of music, one that is inviting and without judgement or disrespect for those who might not share it.
A note about Chaste: There's no on-page sex, though it's clear that Luke's twin is sexually active with his boyfriend. There's no detail shared, mind; just that they've been together for a long time and that they share intimacy. Luke and Vada start with a tentative friendship and both are hesitant and careful, so we get to the I Love You's before they become physically intimate (beyond some kissing).
