Unbreakable

Rate this book
The girls of Unbreakable Starlight were part of an ancient tradition of magical warriors defending the Earth from the forces of the Outside. They knew their powers and their place, and they planned to fight to the very end. They just didn't think the end would come so very soon.

And they never dreamt that when the dust settled, two of their members would be the last magical protectors in the world.

For Piper, her time as a member of Unbreakable Starlight was the best part of her life, the first and only time that she had been truly happy. She'd had friends, she'd had powers, and she'd had her animal companion to make sure that she understood the patterns she saw in all things. Until it all came crashing down.

For Yuina, whose sister died on the night of the assault that killed most of the world's magical protectors, forgetting what she used to be is all that's mattered to her for years. She's been trying her best to toe the line and be the good little symbol of a forbidden calling that her government wants her to be, and she'll keep trying even if it kills her.

But magical protectors existed for a reason, and even if they've all died and the heralds who used to invite replacements to the fight have been forced into hiding. And if the magical protectors aren't holding the line against the Outside, who is?

Lines exist because somebody drew them, and now, with the world left undefended, the lines are getting blurred. Soon enough, something's going to break.

We made a vow, unshakable:
In starlight, we're unbreakable.
We’ll protect the world with all we are,
And when we fall, we’ll fall like stars.

Mira also writes as Seanan McGuire.

Born and raised in Northern California, Mira Grant has made a lifelong study of horror movies, horrible viruses, and the inevitable threat of the living dead. In college, she was voted Most Likely to Summon Something Horrible in the Cornfield, and was a founding member of the Horror Movie Sleep-Away Survival Camp, where her record for time survived in the Swamp Cannibals scenario remains unchallenged.

Mira lives in a crumbling farmhouse with an assortment of cats, horror movies, comics, and books about horrible diseases. When not writing, she splits her time between travel, auditing college virology courses, and watching more horror movies than is strictly good for you. Favorite vacation spots include Seattle, London, and a large haunted corn maze just outside of Huntsville, Alabama.

Mira sleeps with a machete under her bed, and highly suggests that you do the same.

magical girls, but make it about revenge <3

[march 29th, 2023] as of today, you can still get the the signed limited version from subterraneanpress.com! (and this is the only way to get a physical copy of this book bc it's only published through them! - you can get the ebook from amazon, but it is the same price on subterranean and i just recommend going through them for either version!)

Did you watch Sailor Moon growing up? Did you then move on to Madoka Magicka? This is the next step in that evolution.

The horrors of being a child soldier balanced with the magic of being a child and drawn by the sparkle and promise. The understanding of what it means to lose but why we still stand and fight, all mixed with an amazing look at what would make a magical girl setting tick and how the government and society would respond to such things.

Grant/McGuire shows a great love and command for the genre that any of us who grew up waiting for our companion to show up will appreciate.

This wasn't entirely what I expected, but I liked it. It's part of this micro-trend looking at the adult lives of children or teens who became superheroes or saved the world in some kind of way. In this case we're following two women who are the last remaining of a group of super-powered kids that the government now has locked down after some kind of catastrophe. I don't want to spoil anything, but I like how this navigates the lines between childhood and adulthood, how we deal with our trauma, complicated relationships, bravery, and sacrifice.

This is a good short novel about a team of magical girls who try to save the world despite government interference. It's thematically similar to the Velveteen stories that appeared under Seanan McGuire's own name, but in a manga/anime universe rather than a comic book superhero reality. I felt a little lost, as I'm not familiar with those foundations, but it's well written if not especially memorable.

Mini blurb: The last two magical protectors of the world, broken and years removed from the version of themselves who fought to defend it from the Outside, are now hostages of an obtuse government who made their calling illegal - but their kind is still the only hope to keep monsters at bay...

***

Yet another Grant/McGuire novella that could have been a whole 300-page-long book, or even a series, and it would have been amazing...except it's half the length, and it's fully realised and...amazing? Seriously, what's her trick?

Drawing on the "chosen one/magical kid protector" trope (complete with animal companions - sort of - and sparkly outfits), the author delivers a juicy twist that - very much like her Wayward Children series - looks at the aftermath of things, only this time from an adult (and jaded...or maybe not) point of view. What happens when your connection to the magic (and the horror) gets severed? and what happens to the world you were tasked with protecting? With inventive, complex mythology and characters not "likeable" per se, yet able to steal your heart, Mira Grant devises another TARDIS-like story that's so much bigger on the inside - dark and funny, heartbreaking and hopeful, entertaining and thought-provoking. If she ever gets to write more in this universe, I'm happy. If she doesn't, this one is perfect (as open-ended as it is), and I'm happy.

(Fun fact: There's an animal companion in the story whose pronouns keep changing from "he" to "she" and back again - it sounds like the author created it as female and then decided he was better off as male for some reason, but in some instances, the female pronouns escaped revisions, once even in the same sentence where the male ones were...).

Note: definitive review (due to time commitments, I've decided not to write full-length reviews anymore for short stories, novellas and anthologies, except in special cases or unless they're part of a series).

It's always fascinating to see the divide between when Seanan writes under her real name or under a pseudonym. For Mira Grant books, there's always a bit more of a lean into science (here specifically - biology of the monsters that magical girls fight and the mechanics of how the mascot creature's invitations work!), as well as Do Not Trust The Fucking Government. Love that we get the duality of being the unwilling government spokesfigure and the person who can't feel pain and is an expert tactician using it to dissociate and accidentally give herself a UTI. Just a fantastic, fun read, and something I've been looking forward to for a while.

An absolutely fantastic premise that I'm not sure Seanan McGuire/ Mira Grant really knew what to do with after the very strong beginning. She knew she wanted to write a grittier/ adult-er Puella Magi Madoka Magica (she's definitely watched that show), but after taking the scenic route throughout the book, we pretty much end up in the same place and same status quo by the end.

So, great premise, meh execution. Just go watch Puella Magi Madoka Magica.

Adult magical girls dealing with trauma after the horrific end to their adventures and dealing with governments trying to end the cycle of magical children being chosen to defend earth against vast entities from outer space
I liked the originality of it and the darkness !

4-4.5ish stars. I really enjoyed this. This follows two 'magical girls' (think of them like a girl gang of superheroes, kind of like sailor moon) in their adulthood - in the after of when the monsters were beaten off of earth but now what happens like 10 years later. It's a really interesting thought experiment. This has a LOT to say but also is nuanced. It takes on how these 'magical girls' are sucked in with cute animal companions as children into essentially making lifelong commitments and becoming secret child soldiers, but also that came with some good things for the girls oftentimes (plenty of bad too), and importantly that was the only way to protect earth as far as they knew, and how do we reckon with that as a society who says they care about children and want to protect them? It's really interesting. I think this story fits the novella length pretty well, but I secretly am hoping it leads to bigger book or more stories - it could have been longer and I would have eaten it up too. So interesting and the main characters while not always likeable in the traditional sense I really liked them and found them compelling. Also, short book less than 150 pages! But it's only available as an ebook currently I believe since it was published by a small indie press (subterranean press). Also, I am obsessed with this cover - I love it so much.

Seanan McGuire is very prolific. I sometimes wonder if she ever sleeps. I haven't liked her popular long-running series (October Daye, InCryptid), but I think her Wayward Children series is excellent and everything written as Mira Grant is great. One thing that I enjoy is her fresh take on classic story types. In this case, it is a story about "magical children" who protect our world when given powers by mystical companion animals. In this brief (~114 pages) story she takes the classic tropes and turns them into an engaging and new version of this genre. As with other short pieces by Grant/McGuire, I'm hoping this may be the foundation for a longer story or novel.

Great Variation on the Magical Girl story

The author has taken the magical girl trope, popularized in manga and anime, and told a darker story than the usual hearts and friendship. The story ends in a satisfying manner, but I would not mind seeing the author continue writing for this universe.

A little more exposition than I’m used to from Grant/McGuire, but this was still an enjoyable subversive take on the “magical girl” trope. I hope this is the first in a new series.

Not what I usually read - and had I understood the subject matter before reading, I probably wouldn't have begun - but by golly it was a good read! Although it felt as I was reading it that there was mad, continuous action, I was surprised to discover at the end that there were really only three or four things that happen!

Book Summary:

Unbreakable Starlight was one of many groups of girl warriors tasked with defending the planet. Unfortunately, their name was not quite accurate, as most of the group fell - alongside every other warrior.

Only two survived the massacre. Piper and Yuina. Now the government has stepped in, helping to prevent a new wave of warriors from rising up. This means Piper and Yuina must be controlled, their voices carefully overshadowed.

My Review:

Wow. Mira Grant/Seanan McGuire knows how to craft a tale! Unbreakable is one of those books that will obstinately suck you in. Given how the story starts, it's hard not to feel that pull. It's hard to look away once the depth of what happened is clear. There's this compulsion to find out what happens next, not to mention a need to understand why it happened in the first place.

Unbreakable has solid Sailor Moon vibes, though there are a few darker twists. Think teenage superheroes, but there are heavy consequences – most of which have already struck. It's an interesting foundation for the rest of the story.

This novella does have multiple POVs, though I would argue that Piper is the primary perspective. Yuina also gets a chance to show readers her story, which is greatly appreciated. So this is a must-read if you enjoy that format.

Honestly, I just wish there was more of this. I know it isn't needed; the ending told me all I needed to hear. But I really enjoyed the world, the magical setup, and the characters. Thus, I want more.

Highlights:
Magical Girl Syndrome
Urban Fantasy
Sailor Moon Vibes (With a dark twist)

Trigger Warnings:
Character Death
Animal Death (of a sort)
Self-Harm/Injuries

This was genuinely everything I wanted it to be and I really enjoyed reading it. The author knows how to deliver a well executed story in a short amount of time and this book is the perfect example of that.

An interesting take on the "what happens after we save the world" trope and the perfect (for me at least) mix of magical girl, Buffy, and fairy tale inspired world building lore mixed with a boat load of trauma. A little preachy perhaps, but I liked those bits too tbh. Thoroughly enjoyed this.

As someone who grew up on a healthy diet of Sailor Moon, Precure, and Madoka Magica, this was delightful. Unbreakable takes a pessimistic yet realistic look at how magical girls would be treated in our world, when tragedy strikes and bureaucracy steps in to point fingers and cast blame. Throw in a little bit of cosmic existential horror reminiscent of Yuuki Yuuna or Madoka Magica, and you’ve got a heart wrenching story about how two grieving girls decide to take their lives back for the first time in 13 years.

13 years ago a group of child soldiers was killed in Seattle. Only two were left standing. This wonderful novella turns the "magical girl" trope on its head and rips your heart out as you see what's left after the glitter fades.

I think we get about as much text about one of the characters' urinary tract infection as we get interesting material.

Feels to me like the author was inspired by Puella Magi Madoka Magica, but didn't want to do the hard work of writing an ending.

This was an interesting book and also a very sad one. I keep thinking about the social implications of the system where children are offered an opportunity to essentially become superheroes. Of course many of them agree (and of course there would be all kinds of propaganda encouraging it) even if it means their eventual deaths because superheroes are cool and you don't really have an appreciation of what death is at that age.

I don't think it was mentioned, but I'd be surprised if there wasn't something for the family members. The heralds promise they'll be safe, but I don't think there was anything like a government stipend or death award or anything.

It sounds like it is truly meritocratic in the sense that heralds only offer the job to children who have the innate talent they're looking for, but it's also important that they only make the invitation to children likely to say yes. I think both of the survivors didn't have much in the way of stable homes but I can't remember if that was true of everyone. I can see where the children of wealth and privileged are both watched like hawks and have it drilled into them that they have to say no to any invitation.

Have I mentioned I love magical girls? Leave it to Mira Grant to write a heavy story about the last two surviving Chosen (because not all magical girls are girls - a lovely, lovely addition that is pointed) and their lives thirteen years after the final fight. I loved the Sci-Fi spin Grant took on the magical girl genera and the cute little mascots running around giving magic powers to kids.

It actually really made me think about Chosen Ones by Veronica Roth, a book I also adore. There is something about teens with superpowers who survive the tragic death of their friends growing up and still choosing to keep fighting for the world even if the government would much rather hide they disappear or play nice with the propaganda machine.

Impossible to put down and impossible to forget once it’s over. My only complaint is I wish it was longer or we had more stories in this world!

Sometimes, Seanan McGuire works are insidious. I feel like I read them and get a little confused, and then reread them and then everything is perfectly clear and why did I have a problem in the first place? I think it's something to do with the sentence structure, but I still haven't pinned down what.

The short works do a lot with a little, more than one fast read reveals. In this, there's a lot of Sailor Moon and a little bit of Buffy influence, I think (I couldn't stop thinking Merit/Merrick), which is fun, as much as a story about PTSD can be fun. The more that gets revealed, the more interesting it is, but honestly, this feels like a story where most of it is revealed to the reader, not the characters, and I can see people not being interested in that. Their mistake. It's a fascinating world and getting to dip into it is worth the time.

I love stories about magical girls, and I love subversions. This is an ultimate subversion on par with Magica Madoka. There's an almost V for Vendetta dystopian politic to the setting, and Mira Grant does an amazing job delving into relevant lore, all in an extremely engaging way.

This novella feels like what would be episode nine or ten of a twelve episode anime. Piper feels like the mentor character from a different story, with the novella being the flashback/backstory episode which reveals her history and sheds important light on the overall story. I absolutely adored every moment with this book to the point I can't stop thinking about it. I really want this to be the lead-in to a full length novel. The setting is so fascinating, and the story's ending leaves things begging for a sequel.

I'm a little surprised at how Seanan McGuire was able to grab the "magical girl" trope and write the most boring, infodumping and shallow despiction of it.

I've read her Wayward Children series and while I've not liked all of the books, I've enjoyed her analysis of portal fantasy+chosen one (even if I cringe at how heavy handed she can get with the moral message she wants to portray on each book and she tends to overexplain and infodump as if readers are not smart enough to get it if she doesn't) so I was excited to read her take on the magical girl trope and was bored and frustrated while reading this book. It only made me want to re-read the Sailor Moon manga, or watch Sakura Card Captor to clean my palate.

Magical world saving powers given to children. Over and over throughout history like he girls of Unbreakable Starlight. But the end of the world came, and so many went down fighting... that there are only two left. But now Piper and Yuina aren't even speaking to each other and the government is trying to control and rehabilitated them.

Why I started this book: I have a huge stack of library books and a growing list of ARCs so it was the perfect time to ignore all of them and read something else, like this ebook I purchased ages ago.

Why I finished it: This was a shorter book than I expected which helped me fly through it. Interesting to imagine what after saving the world... how many people would blame you and would you blame yourself?

"Despite everything that's changed, the invitation remains a binding contract and a promise and a death sentence, all at the same time."

What if you took the basic concepts of magical girl shows like Sailor Moon and Puella Magi Madoka Magica, and tossed in a bit of cosmic horror mythos into the mix?
Unbreakable has amazing characters and great world building (the concept of magical girls as warriors against entities from beyond our comprehension, invitations as conduits for power, etc). The writing manages to switch between funny and tragic so well, and you feel connected to the characters. This works as a standalone work, but I would LOVE it if Mira Grant ever revisited this world for more stories.
