This is the diary of a self-centered 16 year old (redundant, I know) whose world changes. That's literal, not a figurative overstatement: something crashes into the moon, which changes the moon's orbit and wreaks havoc on the planet around which it orbits.
Did you know that I keep emergency food and water in the basement, that I chat casually with the Red Cross volunteers at community festivals? Not only do I have a hand-crank-powered-flashlight-and-radio, but I know where it is right now. Just writing that down makes me want to make sure it is where I think it is....just in case. This book made those "just-in-case" parts of me, the Worst Case Scenario thinker, go absolutely crazy. I had to refrain from writing down exactly what I thought their supplies would be, and how long I thought the supplies would really last. I couldn't stop myself from "idly" perusing several astronomy and physics boards to see the truth of the science behind the plot. (At some other time and place, I could summarize what I found, if you--dear reader--so wanted.) In other words, this book hit the panic button lying only slightly hidden from view.
The book is probably better enjoyed if you aren't obsessing about the possible realities. Miranda is an interesting enough character. She is selfish a little longer than is comfortable, but she does ultimately have an interesting story to tell. She remains a relatively believable teenager, which I think keeps the reader along with her.
I'm not sure that I'll read the sequel. This makes for a pretty good stand alone book, for one thing. For another, I'm not sure that my basement can handle another doubling of my emergency supplies.

A bad mouthed mercenary with a dark and mysterious past. What's not to like about that? A very interesting world and magic system. I am very curious to see where the story goes from here.

Deliciously chaotic and bloody and queer

This is kind of a hard one to rate. I had a pretty hard time getting sucked in early on with how all over the place the beginning of the book felt. I really liked the world building and Sal, but it just felt like the story was trying too hard to be too fast paced from the beginning and not able to focus on much depth. As the book progressed, though, I got more invested, but it wasn't until fairly close to the end when more of Sal's history is revealed.

I imagine I'll pick up more of this and hope the rest of the series sticks with the slower paced feeling towards the end.

Book is kind of shit tbh.

There is some cool world building-- I did like that part-- but it reads like someone trying to prove that their badass OC is actually really cool and badass, you can tell by all the badass lines he wrote. I had to go to the doctor because I rolled my eyes out of my head. The character motivations also kind of fell flat most of the time? Like they were mostly there to further the plot. Queer character are always welcome, but goddamn is their story arc as rote as possible. Oh really? Is there a choice between getting revenge and living a nice life with a person who cares about you? Do they go over the same conflict 10-15 times? Bad.

Sal the Cacophony is a gunslinging wizard-hunter on a mission of vengeance. Armed with a giant sentient handgun, her targets are seven outlaw magicians: vicious killers on paths of destruction through the broken world of the Scar. This book is brutal, bloody, and violent, with big battles and lots of action, but it also explores the toll that violence, betrayal, and death take on those who experience them. With rich and inventive worldbuilding, snappy dialogue, and characters with surprising humor and heart, this is the beginning of a great new fantasy series you won’t want to miss.

I listened to the audiobook and it was excellant. Definitely looking forward to the next volume.
