I loved reading this book! I love Mira Grant's writing so much, under this name and as Seanan McGuire. This alien story sounded so interesting, and it was such a great moral conversation that was amazing to read!

The idea of an alien invasion, that starts off with humans being replaced by aliens, and then said replacements having the urge to tell their story, that they are aliens? It's such an interesting idea, and a pretty scary one.

Stasia isn't sure if she's telling the truth when she says she's an alien. But then a signal is received and she understands it, that her people are coming to Earth. I really enjoyed being in her head as the time ticked on towards the invasion, and the found family that she had.

There's a big question of morality, of how they took over the humans that they did, as well as which side were they going to be on, the aliens, or the humans that raised them, It was such an interesting dilemma and would've been horrible if it'd been real. It was such a great horror element of this book!

I had so many questions, about how the whole system worked, why it was happening like it did. As we got answers, it was really well done, but again, horrifying. I wasn't sure where this book was going to go, but I was along for the ride.

Loved reading this book and I can't wait to read more by Mira Grant!

We follow Stasia, a normal human woman. She hates her job, most people, and loves her cat more than most other things. She also is an alien/plant being from another planet, and she's patiently waiting for their return.

I adored this book. The light, irreverent tone with the backdrop of the end of the world is right up my alley. Overgrowth explores complex relationships and what it means to be a citizen of earth. The communication in the main relationship was something I enjoyed reading (and strive to achieve). I think keeping your significant other through the end of the world and also learning you're not of the same species is incredibly impressive. The found family and different character relationships were well explored. Mira Grant also has this incredible knack of inventing the science for her different creatures that have me questioning if it's possible. All in all this is a lighthearted (relatively) apocalypse story that I will stay recommending.

Thank you to Netgalley and Tor for the e-arc in exchange for a fair and honest review.

Mira Grant does it again! (And seriously, can we please get more mermaid stories too?)

With Overgrowth, Grant flips the script on the classic alien invasion trope, crafting a story that’s equal parts touching, terrifying, and utterly captivating.

We’re quickly introduced to Anastasia Miller—or “Stasia” to those who know her—a young woman whose life changed forever when she was “hatched.” As a child, a stray alien pod landed in the forest near her home, embedding its essence into her being. Ever since, Stasia has been trying to explain to the world who she truly is, but no one takes her seriously. At best, they find her a bit eccentric; at worst, she’s dismissed as the oddball spouting sci-fi nonsense.

When a long-awaited alien signal finally broadcasts across Earth, Stasia knows she has been called. Together with her boyfriend, she races to Maine, determined to uncover the truth about the signal and her origins. What they find there is both thrilling and terrifying: a growing community of others like Stasia—people who were also “hatched.” Among them are potential allies, dangerous foes, and mysteries far deeper than anyone could have imagined.

Grant’s ability to blend visceral horror with emotional resonance is on full display here. The story moves at a breakneck pace, yet it never sacrifices depth. Stasia’s journey is as much about understanding herself as it is about survival, and the relationships she forms along the way—both human and alien—add layers of complexity to the narrative.

Overgrowth is more than just an alien invasion story; it’s a deeply imaginative exploration of identity, belonging, and the unknown. Mira Grant once again proves why she’s a master of her craft, delivering a novel that’s as heartfelt as it is horrifying.
Whether you’re a long-time fan or new to her work, this is a must-read. And yes, it’s 100 percent awesome.

This was creepy and funny and so so interesting! The beginning immediately hooked me and I was engaged the entire time. I don’t usually read too much sci-fi so this was a treat!
