Zero Sum Game

Pros: fast paced, protagonist is ‘good at math', interesting characters

Cons:

When Cas Russell takes the job to ‘retrieve' Courtney Polk from a drug cartel, she assumes it will be a simple job. Because she's VERY good at math, able to calculate vectors on the fly, making her dangerous in a fight. But she didn't expect her mentor Rio to be working for the cartel. And when the woman who hired her turns out to be more than she seemed, Cas discovers she's become a target of a mysterious organization, one with people who also have super powers.

This is a fast paced read that took me two days to get through. There are so many twists that it was hard to put down.

It's an interesting cast of characters, as none of them are really ‘nice' people. They've each got their good and bad qualities. Cas is a morally grey individual, who has no problem killing but also has some lines she won't cross. Despite being a psychopath I mostly liked Rio. There's a Dexter feel to him, as a man who's using his baser urges for what he perceives is good. Arthur Tresting balances Rio on Cas's other side, being mostly moral, but willing to bend the law when necessary and pretending he doesn't know about or see most of Cas's casual crimes.

I loved that Cas's ‘superpower' is that she's just REALLY good at math. Like, so good she can do multiple calculations at once and so dodge bullets and make fancy trick kicks to take out opponents. The fight scenes are surprisingly entertaining.

I thought the rabbit hole of secret organizations was handled well, as was all the self doubt brought on by Dawna's influence.

I really enjoyed the book.
