I very rarely read books electronically. I know, I know … but I don’t own an e-reader, and I spend way too much time staring at screens already. But I was stuck on the plane Sunday evening with nothing to read, so I pulled up my copy of Zero Sum Game [Amazon | B&N | Kobo], by SL Huang.
I finished it two days later.
Here’s the official description:
Cas Russell is good at math. Scary good.
The vector calculus blazing through her head lets her smash through armed men twice her size and dodge every bullet in a gunfight. She can take any job for the right price and shoot anyone who gets in her way.
As far as she knows, she’s the only person around with a superpower … but then Cas discovers someone with a power even more dangerous than her own. Someone who can reach directly into people’s minds and twist their brains into Moebius strips. Someone intent on becoming the world’s puppet master.
Someone who’s already warped Cas’s thoughts once before, with her none the wiser.
Cas should run. Going up against a psychic with a god complex isn’t exactly a rational move, and saving the world from a power-hungry telepath isn’t her responsibility. But she isn’t about to let anyone get away with violating her brain — and besides, she’s got a small arsenal and some deadly mathematics on her side. There’s only one problem…
She doesn’t know which of her thoughts are her own anymore.
This is a fast-paced thriller with lots of action and fighting and a diverse cast and secret organizations and subterfuge and general sneakiness and ass-kicking. Cas is cold and efficient, but with just enough humanity to keep her somewhat sympathetic. Her two companions bookend her nature quite well: Rio is basically a serial killer channeling his violence toward the bad guys, while PI Arthur is the heart and morality of the group. The conflict between them is very well done, particularly Arthur’s horror when he realizes who Cas’ friend is.
I’m also quite fond of computer guru Chester, a wheelchair-using geek who reminds me of Oracle. (With the caveat that I haven’t read Oracle in the comics; I’m just familiar with her character from talking to my fellow geeks.)
The overall conflict is perhaps familiar, but still engaging: a group with mental superpowers is manipulating the world to make it better, even if that means brainwashing and killing those who get in the way. It presents some good ethical dilemmas, since the antagonists have set things up in such a way that hurting them could actually help other villains.
The one problem I kept stumbling over was Cas’ powers. I can buy that she’s a math supergenius, but instinctively seeing and understanding the math of the world around you is one thing. Being able to apply that math to put every bullet exactly where you want, to hit a kid with a tennis ball after three ricochets, to weave a motorcycle through traffic at insane speeds, these things kept snapping my suspension of disbelief. The physical aspect is a whole other superpowered skillset, one that’s never mentioned.
On the other hand, her superpower is math. How cool is that?
We do get hints about Cas’ backstory toward the end, but we’ll have to wait until at least book two for the details. Overall, the ending wasn’t as satisfying as I’d hoped, but again, I suspect that’s because Huang is setting the groundwork for future books.
Nitpicks aside, I devoured this book, and I’m very much looking forward to the sequel, Half Life, which should be out in January.
