Yep. I gave a Mira Grant book 2 stars.

It pains me to do so, it really does, but this series, in general, has not impressed me at all. Parasite/Symbiont was intended originally to be a duology but it has now transformed into a trilogy with Symbiont becoming nothing more than a seriously massive tome of filler. It was a huge undertaking to get through this (a total of 23 days which is fairly unheard of for me) but there’s no denying that it definitely lacked direction.

Wrong. They moan, so you should be able to simply use your ears rather than endangering the dog. Also having a barker when you are trying to be sneaky is probably not a good idea.

What's that? I actually finished a book?

I know I was surprised too.

'Twas a good book too. Not as good as Parasite, but a solid sequel. I'm still on board for book three, coming at my reading list in 2018!

The Symbiont Drinking Game
One shot whenever Sal faints, passes out, or is tranquilized.
Two shots whenever Sal descends into the "hot warm dark".
Read this way it can be five stars and a blessed brake from holiday mayhem.

The best thing about this book is its irreverence. There's a character who is fully convinced that he is living a video game because that makes more sense than a parasitic zombie apocalypse. In the book he's nuts but as a reader you laugh because it almost does make more sense

Love, love, love. Will write a proper review later. <3
So, the first book ends with "Nathan pulled out a key as we walked toward the bowling alley door. [...] Anything else I might have had to say was lost as he opened the door and I was swarmed by Beverly and Minnie, both wagging their tails in frantic delight."
The second book starts with them leaving the bowling incint to get back the dogs (Beverly and Minnie) from their apartment..

Well, I guess this could have been accomplished if the author and the entire editing team had sudden amnesia..

I'm going to go out on a limb here, but I really didn't love this. I'm a huge fan of Seanan's work normally, but this one felt over-long and drawn out with just too much standing around in rooms vacillating about what to do next when only the bad guys seem to have a plan.

The first one was alright, although the "big reveal" was completely obvious to everyone but the main character, who even reflects in this book that retrospectively even she thought it was obvious. This next one has Sal and Natha

Usually when a duology becomes a trilogy or a trilogy becomes a more lengthy series overnight, I grumble and complain and become instantly resentful of both the author and the publisher. But when I discovered that this duology somehow grew to become a trilogy, I felt nothing but satisfaction and joy. More books from Mira Grant are always good news to me. In fact, if Parasitology suddenly became a 180 books long medical thriller/soap opera hybrid, I’d still be a happy camper. That’s how much I ad ...more

3.5 stars. Not quite as good as the first one but a solid middle book. Lots of character development in his one. Not a whole lot of action until the end and then it's a pretty big cliffhanger.

This review appears on Happy Indulgence. Check it out for more reviews!

Only Mira Grant could write a series about tapeworm horror, and make it compelling, intelligent, well thought out and absolutely terrifying.

The Parasitology series explores a world dominated by science, where people rely on tapeworm implants for perfect health and longevity. While Parasite explored how this technology was invented and how it was adopted across the globe, Symbiont explores the detrimental and disastrous effec

I'm not sure how to process this story... it's my worst nightmare, and yet in a sense I have to root for that!

Alright, so before I dig in to the meat of this book I have to warn you that part of what I'm going to say will be about things that were revealed in Parasite, the first book in this series. If you haven't read that book, don't read further!

I seriously do not know where I stand on this book. Mira Grant is so good at development. It's not so much that I believe that this world could reall

I didn't think the book was perfect, but it was entertaining and I'm quite looking forward to the next one.

If you have not yet read Parasite I suggest you swallow the red pill and slip down the rabbit-hole that is Grant’s brilliant mind and join the rest of us in this frighteningly real apocalyptic future.
This is your last chance. After this, there is no turning back. You take the blue pill -- the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill -- you stay in Wonderland and I show you how deep the rabbit hole goes.- Morpheus, The Matrix, 1999

I didn't love it as much as the first one. Maybe 3.5 stars?

I think Mira Grant could write a traffic ticket and I'd read it. :D I've been anxiously waiting for this book since I finished reading book one, "Parasite", in October of 2013. I was delighted when it was announced several moths ago that instead of two books, Grant will write three in this series. Frankly, I doubt she could have wrapped this up in two books. And these books are not short. "Parasite" was 512 pages and "Symbiont" is 516 p

This is the second book in the Parasitology series by Grant; this was originally going to be a duology and was extended into a trilogy. The third book, Chimera, is set to release late 2015. This was hands down my least favorite book Mira Grant or Seanan McGuire (her other pen name) has written. I am a huge fan of all of Mira Grant's/Seanan McGuire's other books. For some reason though this series is just missing the mark for me.

Sal is coming to terms with the fact that she is no longer human. He

2.5 stars: enjoyable, but quite a few things could have been avoided or handled differently. Also, not a fan of characters fainting often, or getting in kidnapping situations once too many. But I think part of this can be chalked up to "second book syndrome".

I love that the first couple lines of the synopsis are all shouty caps about how terrifying Mira's books are, hah.

When looking for someone to trust with your health, choose SymboGen. Because if you can't trust Nature, who can you trust?

After I finishing this book, my first thought was, the books are not named appropriately... the #1 should have been Symbiont 'cause the original purpose of D. symbogenesis parasite was to have symbiont relation

On the one hand, I really enjoyed Symbiont. On the other, though, it did disappoint me. After loving Parasite on my reread, I find myself back here, once again disappointed in Parasitology. Newsflesh is pure perfection, and this series is not managing to achieve that magic again. Symbiont is clunky and second book syndrome all the way.

For one thing, not much that’s plot essential really happens in Symbiont. The whole book is plotting fail level video game, where Sal is always either on

At first I thought this book had an especially bad case of middle-book-treading-water syndrome, and then I learned from other reviews (and it seems to be confirmed in press releases from Orbit when the first book was announced) that this wasn't even supposed to be a trilogy in the first place. And all I can say is that if you look at a duology and think, "What this really needs is an extra 500 pages of absolutely nothing happening so we can sell more copies," then you really deserve nothing more ...more

It pains me to say this, because I have devoured Mira Grant's work at an alarming pace with every piece I've picked up, but I found Symbiont clunky and uninspiring. :(

I find it hard to put my finger on everything I was not happy about, but among my issues:

-Sal is truly developmentally broken. Beyond the obvious intent of the character, she quite frequently takes two steps forward in one scene, then anywhere from 1-5 steps back in another scene. I found this immensely frustrating and exhausting t

Still entertaining enough, but some things got on my nerves.

Too many reminders about what happened earlier/in the previous book. The reader can sometimes use some help, but here it felt like the reader was considered a complete idiot.

Too many references to the "open doors" story the characters encountered. Ok we get it, it was a nice metaphor for the one moment in book 1. Move on already.

Too many times referring to a dog as "good dog" for every action or trained thing of one of the dogs.

Very repetitive. Tells us the same things over and over. If it mentions something once, it mentions that same thing again and again.
Did I mention this book is very repetitive?
After reading: Do you see the edit below that I made back when I first read Parasite (Read my review maybe and was waiting eagerly to read the 'then' last one? (It's a trilogy now sigh). I think I'm gonna have to copy paste the whole thing since this shit is still stuck on yet another freaking cliffhanger!


Also, that awkward moment when you realize that even a tapeworm has a boyfriend but you don't.

I read Parasitology last year and loved it, loved the science and the amazing premise of the different "kind" of zombies and the starting of the apocalypse.

After the ending and revelations I was really looking forward to reading Symbiont, the sequel and I'm very happy to report that it didn't disappoint at all!

Symbiont started with Sal dealing with the revelations of Parasitology and even if Sal keeps having her doubts and is somewhat paralized, she does a pretty good job at figuring out what re

Tansy’s story is shocking and heart-breaking. Her viewpoints are probably the most powerful parts of this story, even if they are limited. The world Sal now lives in is starting to become very cruel indeed and there’s some hard to swallow scenes. Fishy, new to the scene, is delusional, refusing to accept the apocalypse is really happening and he thinks he’s just inside a video game. In some of the final chapters, this becomes endearing and also made me chuckle in the face of imminent doom.
