Immunity by Erin Bowman: An Underappreciated Sci-Fi Thriller Duology

I read Contagion last year (spoilers ahead for Contagion, book 1, of course!) and enjoyed it, but frankly, I don’t think I appreciated this series enough back then.

I think Contagion and the sequel Immunity bring something special to YA’s science fiction table. I’d categorize it as crossover fiction, branching YA and adult well. I didn’t give this enough credit when I read Contagion, but I see it now.

Immunity and this whole series has something unique about it: it weaves a lot of common YA elements (an entertaining and streamlined story, characters that are extremely relatable, action) with a more adult storytelling style (third person multiple point of voice, slightly on the more technical side).

And it’s not like these elements are exclusive to each category, but they definitely lean one way more than both.

Contagion and Immunity weave YA and adult, and honestly I think it’s a great intro to anyone wanting to move from YA to adult science-fiction. I think this is really valuable and has a lot of potential.

I read this relatively quickly and there’s definitely a lot of action happening. It kept the story from sagging in the middle, although I do admit that I did start to stray in the ¾ mark, but came back pretty quick.

It’s a fun concept and full of action and that keeps it fast-paced. So if you love action, definitely check this out!

I do admit that I remember…basically nothing from Contagion and I do wish that a summary of the first book was included, but honestly I just kind of went with the flow and it turned out fine. I felt like I read Immunity more for the reading experience than the story, if that makes sense? It had a nice rhythm and made it kind of soothing to read, despite all the things happening.

(If I have to be completely honest, you probably don’t need to read Contagion to read Immunity.)

But yeah! It had a really nice science aesthetic, and obviously if you think too hard about it, you’ll probably find holes, but it kept the aesthetic up well and I found that to be enjoyable.

Also, I totally called the romance (in a good way). As in the f/f one that comes in later. So [insert serious eye emojis] keep an eye out for that!

I do think it had slightly less action than Contagion but it wasn’t a major issue to me. Although there are less zombie people to fight, there’s still a lot of things happening and on a wider scale you get to see the conspiracy, which was nice.

Overall, I thought Immunity was a good closer to the series. Although it isn’t my favorite of all time, I think people with the following preferences would definitely enjoy:

  • someone looking to transition from YA to adult
  • someone who enjoys science fiction and space operas
  • thrilling infections with a story similar to This Splintered Silence

3.5 stars


Thea and Cole are captured and being experimented on, as one of the few who survived the contagion. But this situation is just as dangerous, as they develop new strengths that people want to capitulate on.

However, a greater conspiracy emerges, and Thea and Cole must find more allies to both escape and prevent a worldly disaster from occurring.

With help from a recovering Nova and a medical intern, they escape and begin to fight back. But dangerous new allies and unreliable technologies mean they may not succeed.

Thank you so much to Harper Collins for providing me with an early finished copy in exchange for an honest review!

Have you read any books in the series? What would you recommend as sci-fi crossover fiction?
