I'm really disappointed. This whole book was underdeveloped, both the plot and the characters. Also, I was so distracted by the extreme weird inaccuracies. For instance, going on a major field trip with 70 students and only 1 chaperone? NOPE. Legally, schools can't do that. I believe there is actually a ratio of students to adults that must be met, and one air-headed teacher for an entire band is not it. Also, band (both concert and marching) was a huge part of my life for TWENTY YEARS (with many as an observant sibling, nine as a concert band student, and ten seasons of marching band). If ever there were an expert on band, I would probably be it. And that fact that Liza, the drum major of the MARCHING band, conducts the CONCERT band? Nope nope nope. Mr. Lenny's-dad, do your effing job and conduct them, you lazy a-hole (if you think I'm being harsh, he literally spends the entire book trying to hook up with the faculty advisor for the Athenas). 
 As for the characters, all were flat and woefully one-dimensional. Liza is like Cady from Mean Girls. She plays it off like she's the only one who knows what she's doing, but she doesn't support her friends, has narrow focus, and is just plain mean. I wish she had a Janis Ian to give her a verbal smackdown (her friend Huck tries, and is probably one of the better characters [Russ being my other candidate], but he's just not present enough). I don't understand why (view spoiler)[Russ (hide spoiler)] even likes her because she's so horrible and rude to him throughout the entire book. Demi is annoying in her role as a typical former best friend turned mean girl/queen bee, and Lenny is just...whatever. 
 Finally, everything felt unfinished. The resolution came too quickly and felt insincere. Liza goes from basically bullying (view spoiler)[Russ (hide spoiler)] all week (even though he was never anything but kind to her) to kissing him in a swimming pool; (view spoiler)[the band magically wins the competition (hide spoiler)], and everyone decides that (view spoiler)[Lenny (hide spoiler)] is an ass. I'm not disputing that he is, but everything was rushed. 
 As a side note, I was extraordinarily bothered by one particular scene. Liza is talking to Lenny in the steam room of the ship's spa, and the two of them are wearing towels. It's weird, yes, but I was willing to go with it. What I can NOT just go with, however, is that Lenny's dad (I seriously can't remember his name. It started with a C) gets upset with Liza about the situation (even though as previously stated he's basically been MIA the entire book), "grounds" her, and gives her detention.... but we never see him get upset with Lenny. Yes, it's Liza's pov so maybe he did have a private conversation with his son, but I am very very bothered by this. First of all, it's a misunderstanding. Liza and Lenny were not having a sexy moment, and it could have been easily explained. Secondly and more importantly, I think it sets a bad example by shaming and punishing a girl for the supposed sexy moment, but the guy gets off scot-free. SO. VERY. MUCH. NOPE. 
 I like Lauren Morrill. She's super nice and is a very talented voice in ya contemporary. I liked Meant to Be and REALLY liked Being Sloane Jacobs. I think Trouble with Destiny was a misstep so it won't keep me from reading her future books, but I certainly can't recommend this one. 
 Many thanks to Random House/Delacorte for sending me an arc!
