Lesbian characters? Interracial love? Disability themes? Contemporary YA with a plot?? 
 I don't know how Unspeakable could be any more perfect or progressive. We need more books like this. Hope Rushton plans to write more, because I plan to read whatever she puts out there. 
 The only reason I did not give it a full five star rating was because there were points where Megan's negative thoughts were a bit excessive. However it makes sense for a mentally fragile character to be that harsh to herself. A traumatic event makes her mute, after all. So it suited her -and I forgave it- but those moments were not exactly... fun. A touch too teen angst. Luckily they were few and far between! 
 So beyond that one detail, it was flawless. I already recommended it to friends and I don't plan on stopping.
