Look, I need to have a word with Mira Grant about pacing. Sixteen hours. Sixteen. I've sat through C-17 flights shorter than this audiobook, and at least on those flights something eventually happened — like landing. Parasite has a killer premise that had me hooked from the jump, then proceeded to test my patience like a new private who won't stop asking questions during a briefing.
Here's the thing though — I kept listening. And that says something.
The Tapeworm Pitch That Hooked Me
Granted (no pun intended), the concept is genuinely brilliant. Genetically engineered tapeworms as the future of healthcare? SymboGen Corporation selling you an "Intestinal Bodyguard" that handles everything from allergies to drug delivery? That's the kind of near-future sci-fi that makes the hair on the back of your neck stand up because you can see some pharmaceutical company trying exactly this. I've seen enough government contractors sell miracle solutions to know how this plays out — the sales pitch is always better than the product.
Grant — who's really Seanan McGuire writing under a pen name — clearly did her homework on the parasitology and immunology. The science feels grounded enough that when things start going sideways, when people start going blank-eyed and shuffling around like they've checked out of their own bodies, you buy it. The "sleepwalkers" aren't just zombies by another name. There's actual biological logic underneath the horror, and that made it land harder for me than most outbreak fiction. Face: A Novel hit me with that same gut-punch of body horror grounded in something just plausible enough to keep you up at night.
Sal Mitchell as a protagonist is an interesting choice. She's someone who survived a near-fatal car accident with no memories of her life before, basically rebuilt from scratch by her own implant. So when SymboGen starts circling her like she's a lab specimen worth studying, the paranoia feels earned. She's not just running from monsters — she's questioning whether she can trust her own biology.
Where the Mission Bogged Down
But here's where it lost me, repeatedly: this book needed a tighter edit. Badly. There are stretches — long stretches — where Sal is having the same conversation about trust and autonomy with different characters, and you're sitting there going "Roger that, I got the message three chapters ago." I was listening at 1.25x during a drive out to a client site in San Marcos and even at that speed, certain middle sections felt like we were running in circles. The "big reveal" that the book builds toward? If you've been paying any attention at all — and Grant gives you approximately nine hundred hints — you'll see it coming from about hour five. I was waiting for the book to catch up to what I'd already figured out, and that's a frustrating place to be for ten more hours.
It's the classic first-book-in-a-trilogy problem. A lot of setup, a lot of world-building, and then a cliffhanger ending that says "buy book two." I respect the hustle, but I wish the ratio of setup to payoff was better balanced.
Christine Lakin Carries the Weight
Christine Lakin's narration is what kept me from bailing during the slower sections. She gives Sal a distinct vulnerability without making her sound weak — there's a quiet stubbornness in her voice that fits the character. Her SymboGen corporate types sound appropriately slick and evasive (reminded me of every defense contractor briefing I've ever sat through). And she handles the scientific exposition without making it sound like she's reading a textbook, which is harder than it sounds when you're explaining tapeworm genetics for twenty minutes.
That said, I wouldn't call the performance electric. It's professional and clear, but during those slower stretches where the writing isn't pulling its weight, Lakin can't quite inject enough energy to compensate. She's working with what she's got.
Who Should Saddle Up — and Who Should Stand Down
If you loved Grant's Newsflesh series (which I burned through — Feed is the superior book, fight me), you'll find familiar DNA here. She's got that same knack for taking a horror premise and grounding it in corporate greed and government incompetence. If you're into Crichton-style "the science we trusted is going to eat us alive" thrillers, this scratches that itch. But if you need your thrillers moving at combat speed, this is going to frustrate you. The payoff is coming — just not in this book.
Ranger fell asleep twice during the middle act, and honestly, I don't blame him.
Bottom Line From the Debrief
Worth your time? Conditionally. The premise is A-tier, the execution is B-minus, and the pacing is C-plus. I'm curious enough to continue the series because Grant clearly has a bigger plan, and when the horror elements kick in — the sleepwalker scenes, the body horror implications of what these worms actually want — it genuinely unsettles. But I needed more of that and less of Sal having her fourteenth anxious conversation about what SymboGen is hiding. Bump it to 1.25x minimum, commit to the long haul, and know that you're investing in a trilogy, not getting a standalone experience.
