I wanted to love this, but despite the intensely high stakes for the narrator, the pacing of the first third of the book somehow felt glacial. I recognize I was supposed to be appreciating her budding relationship with her friend Maddie, but there were so many details about old planes, airfields, motorcycles, etc, that I got bogged down. There was also a particular conceit of the narrative that I didn't like. (view spoiler)[Julie including herself as "Queenie" in the third person, even after admitting it was her. It felt weird to me. (hide spoiler)] 
 Still, I managed to get past these things and ultimately enjoyed the conclusion. I even got a bit teary-eyed, I admit. I've been waffling between a 3-4 star rating and have decided on 3, since I nearly abandoned the book at one point. I suspect it would be much better upon rereading.
