Disclosure Note: I was given a free digital copy of this book for review. Thrillers aren't typically my cup of tea. I most often stick to non-fiction, and when it comes to novels, I tend to favor books that use the plot to develop characters, rather than the other way around. But when Amy Rogers sent me a copy her novel Petroplague, she billed it as "fictionalized science, not science fiction," and I was intrigued. Coupled with the fact that it's a book about bacteria and about energy and about science, I couldn't say no.
Some spoilers follow, but as we now know, spoilers don't actually spoil your enjoyment, so read on (and I won't give away the ending). Petroplague tells the story of Christina Gonzalez, a diligent grad student from UCLA, genetically engineering a bacterium that can metabolize long-chain hydrocarbons (like those found in oil and tar) and turn them into methane (natural gas). The goal is to use these bacteria to extract energy from tar sands. But everything goes horribly wrong when her test site is sabotaged by an ecoterrorist, loosing her bacteria onto the streets of LA, where it gobbles up everything from gasoline to jet fuel, bringing the entire car-choked city to a screeching halt (with a healthy dose of methane explosions thrown in for good measure).
- The story is fast paced and rarely dull. Chapter breaks seem to come every other page (this is literally true in some cases), but the action pulls you forward. As I said, I'm not a general consumer of thrillers, so I couldn't say if it stands out in this regard (there's a couple good Amazon reviews with readers who seem more familiar with the genre). So onto something I know more about:
- The science is utterly believable (mostly). There are folks working on bacteria that metabolize oil, there are folks working on bacteria that make hydrocarbons. I'm not aware of anyone researching the same thing as the protagonist, but it's in no way unreasonable.
The biggest scientific leap-of-faith is the mechanism by which the bugs get out of control. Lab strains of bugs like this are notoriously feeble (one of the major issues with the commercial feasibility of these approaches), and it's difficult to imagine that a shift from anaerobic to aerobic metabolism alone would turn them into the scourge of LA. Still, it's at least plausible, which is far more than I could say about most fictional portrayals of science.
- Rogers goes out of her way to actually talk about a scientist and the way science is done as more than just caricatures. There are a few problems I had with this (see below), but overall, it's a welcome change from the standard stereotypes. The author herself is an MD/PhD, so she knows of what she speaks, and it's refreshing to see a bit more nuance in the portrayal of researchers (other than egghead or mad scientist). Though the public largely trusts scientists, what we do is mostly a black box, and more humanizing portrayals can only help.
- In several cases, the exposition was a bit obvious. In other words, there were several times when Christina (the main protagonist) was explaining her research or events in ways that were blatantly explanations to the reader, and felt unnatural. I imagine it's quite difficult to explain the science in a narrative without coming across like a textbook, and I don't know if I could have done any better, but there were several cases where it took me out of the story.
- There were a few places where the science is wrong or exaggerated. For instance, when Christina and her boss are trying to determine the origin of the bacteria, they stay in the lab all night doing a bunch of different assays (accurate!) including a microarray to check the DNA of the bacteria (not accurate). A microarray is a way to look at changes in the level of expression of a large number of genes at the same time, but very few labs have their own microarrays, and even those that have their own would be hard pressed to prep a sample, run it, and analyze the data in the course of a single night. But even leaving that aside, though you can use microarrays for genotyping, it wouldn't make sense in this setting. If you were looking at the potential of thousands of different bacteria, that would be one thing, but in this case a simple PCR would be sufficient.
It's a minor point, perhaps all the more glaring because most of the book is scientifically sound, but for all the effort put into getting the science right, minor lapses like this (especially because they are not necessary for the plot) were a bit infuriating.
It's a quick read, and it's both entertaining and scientifically plausible. I'm not thrilled with the idea of freaking people out about engineered bacteria (since I think this is one of the most promising approaches to our energy crisis), but the book is not alarmist, and the positive portrayal of research scientists more than makes up for it in my opinion.
If you're into thrillers, and you like you like your science accurate (as I would hope my readers do), this seems a steal at $5 for the Kindle version, and Amy Rogers told me she intends to self-publish a print version that will go on sale December 1st.
