Book Description: Annihilation meets Day of the Triffids in this full-on body horror/alien invasion apocalypse.
This is just a story. It can’t hurt you anymore.
Since she was three years old, Anastasia Miller has been telling anyone who would listen that she’s an alien disguised as a human being, and that the armada that left her on Earth is coming for her. Since she was three years old, no one has been willing to listen.
Now, with an alien signal from the stars being broadcast around the world, humanity is finally starting to realize that it’s already been warned, and it may be too late. The invasion is coming, Stasia’s biological family is on the way to bring her home, and very few family reunions are willing to cross the gulf of space for just one misplaced child.
What happens when you know what’s coming, and just refuse to listen?
Kate’s Thoughts
I have read a fair amount of Mira Grant, and have mostly enjoyed basically all of the stories I have read! I really enjoyed the “Feed” Series, and also liked “Into the Drowning Deep”, and I always find her horror stories fun and incredibly readable. So when Serena approached me asking if I wanted to do a joint review of her newest book “Overgrowth”, I immediately jumped on board. Sure it sounded a bit more Science-Fiction-y, but at the same time the idea of plant aliens invading Earth sounded a lot like “Little Shop of Horrors”! And plus, it was Mira Grant! I had high hopes!
But. I did not like this book. What did I like? Well, I did like the little nods to “Little Shop”, including Stasia having a cat named Seymour, which REALLY tickled me. And I liked that Grant continues to do a bang up job of having great rep for LGBTQIA+ characters in her books, this time having Graham, Stasia’s trans boyfriend, being a well rounded and compelling player in the story. I even liked the way that Grant draws comparisons between the treatment of marginalized groups being Othered with Stasia and her own Othering as an alien who never hides who she is, and is seen as weird and treated as such by others.
But the not so good. The first thing is that the pacing is a bit stilted. It can go from feeling like it’s lagging and slow, to going WAY too fast by the end (once we got to the invasion itself, VERY close to the end of the book, it was warp speed, and that was jarring). The second thing is that this is definitely more heavy on the Sci-Fi than it is horror, and that genre just isn’t for me outside of some very VERY specific parameters. But the biggest issue for me includes a spoiler, even if it’s very early in the story and will be clear pretty quickly, but still, be warned: SPOILER ALERT. We have a very gruesome scene almost right away in which a three year old little girl gets consumed by an alien plant, in lots of really unsettling and upsetting detail. With little to no warning. This is just the kind of stuff that I really can’t abide anymore in books that I read, and had I known that it was going to include that, I wouldn’t have read it. Is this probably more of a ‘me’ problem than a problem with the book? Yeah, almost assuredly. But it really turned me off, and there wasn’t really any recovery in regards to my reading experience, so my review stands as such.
Will “Overgrowth” work for others? Yeah, probably! But for me, I didn’t enjoy it.
Serena’s Thoughts
I largely agree with Kate. While I have read Mira Grant’s “Feed” series, I’m more familiar with Seanan McGuire (Mira Grant is her pen name for most of her horror and horror adjacent titles) and her fantasy works, all of which I’ve enjoyed to some extent or another. But yeah, this one was a struggle.
Kate already touched on the pacing, and I completely agree with her assessment there. I’ll also add that tonally the book felt equally out of sync as it did with its pacing. It starts out in an incredibly dark and gruesome manner (I’ll also talk a bit of spoilers in my last paragraph and will warn you ahead of time!) and then ends in a way that, I felt, was also pretty dark. But in between it seemed to be almost going for a romcom-like tone? There were a bunch of quirky characters and found family moments and much more emphasis on the love story than I had been expecting. Of course, I’m never one to complain about a love story, but, again, the romcom-like tone of the love story sat uncomfortably alongside the more serious aspects of, you know, the world being invaded by plant aliens.
I didn’t mind the science fiction elements nearly as much as Kate (obviously, since this is a preferred genre of mine). But at the same time, there’s a reason I don’t read horror, and for me, this book highlighted my struggles with that genre. So, it’s kind of funny in how predictably Kate and I reacted, with regards to our priors of genre preference! Mostly, this came down to the darker aspects of the horror elements. By no means do I need every book to wrap up with flowers and rainbows, but I also tend to struggle with the horror genre with the morally grey/questionable/is it really over?? type endings that you sometimes find. And this one…yeah, I couldn’t feel great about any of it. However, I do want to applaud the author for following through on her concept.
Likewise, and here come the spoilers, I had similar feelings about the beginning. Right away, you know it’s going to a dark place in that first chapter. And she GOES THERE. So, on one hand, I can appreciate that she didn’t shy away from the horrific nature of what she was writing. But on the other hand, yeah…I, too, could have lived without reading this scene. I don’t think I’m overly sentimental as a mother, but there are definitely new lines that I really try to avoid crossing in my media consumption, and this was a perfect illustration of that exact line. Beyond the scene itself being hard to read, I never really recovered. I know it’s not the main character’s “fault” that this happened, but I couldn’t ever really invest in her either, with this horrible image constantly in my mind. Like Kate said, this was definitely a personal reaction to this scene, and other readers may not struggle with it as much.
So, there ya go. Unfortunately, this one didn’t really work for either of us. But I also think it’s one of those reads that others may enjoy much more!
Kate’s Rating 4: This just didn’t work for me, in spite of the “Little Shop of Horrors” nods and the well done representation of queer and trans characters. I had high hopes that weren’t met.
Serena’s Rating 5: I think that trigger warnings can definitely go too far and get into spoiler territory sometimes, but one definitely could have been used here! Other than that, some mismatches in tone and pacing also let this read down for me.
