Scrawling out of review because this book actually filled a major void caused by another book with that literally in all ways was trying to be this book, but failed in all aspects. 
 That is to say that if you have to choose between Vanishing Girls and this, my vote is this. Because it did everything better. The genre, the love triangle between siblings, the mental health/rebel teen edge, it was all handled much, much better in this book, and tackled issues of sexuality, drug addiction, and grief in a much less smoke-and-mirrors way. 
 This book was really hard. 
 I went in knowing that this book was going to be hella gay. And it delivered. I am so happy that we finally have a bisexual character choosing between two love interests that have factors outside of gender that make the choice complicated. I still didn't like the implication of her having to choose to begin with, but her choice is the one who's kinda dead (not a spoiler it's the first thing you find out in the book), and instead it shapes her arc around recovery from addiction and letting go of the people she's mourning. 
 At first I found Mina to be the biggest, most annoying bitch in that typical "she was the exciting one and I was the quiet one" stereotype, but honestly, for someone as angry and closeted as Mina I sort of forgave her for it These were two real, well rounded queer characters. 
 It is very high stakes drama 24/7. There's not a lot to cuddle into and savor, but our MC is high on Oxy for most of the flashbacks, so there's not a lot of spare joy to be found. But it's there. I definitely will keep my mind rolling this one around for a while.
