I’m not usually a fan of sequels - I think Jurassic Park (The Lost World, what were you thinking) and Speed (Speed 2, it’s simply appalling) have a large part to play in that, but I read this anyway because, well, it’s @Ronyx, if anyone deserves a chance it’s him. I was not disappointed.
You should definitely read Brittle As A Bird first. Even though this story does well on it’s own, you can’t properly appreciate the broader character development or the painful difficulty of the emotions unless you’ve already seen where they come from. And yet, I feel bad for saying that, because this really is a great story anyway.
As seems typical of @Ronyx, you’re not exactly inundated with rainbows, unicorns, and explosions of glittery joy. In fact, you often have to look really bloody hard to find any trace of their existence at all. It’s too lazy to call it ‘gritty’, but there’s a harshness to the reality portrayed here which for me at least made it all the more enticing. Oh, and, you also get the meet one of the cutest kids ever.
