Cas Russell specializes in retrieval. With skills ranging from hand-to-hand combat to small arms fire to evasive driving, she is a force to be reckoned with… but what makes her special is an advanced working knowledge of all things mathematical. She has an equation for everything. The aiming vector for her snubnose, the results of algorithms to deduce the similarities of millions of seemingly random numbers… all immediate answers ready in her head.
When a new case spirals out of control, Who hired her and why? And who should she trust? The questions keep piling up and these blank pieces drive a narrative that is fun, exciting, and worth every minute of reading. All she can figure out is that her enemy has the ability to influence your every move with a psychic connection and manipulation that her allies will have great trouble competing with.
Zero Sum Game is a novel with slick computer hackers, mathematical-enhanced fighting, and a rocking new character to follow on the hunt. Throw in some great original lines and you have a Marvel-esque action series worth following. Previously self-published and now with Tor, it should get the buzz it deserves.

You say this is a re-release. Was it with another publishing house before, or indie released?

Thanks for checking out my review! I looked into it, and my understanding is that previously it was self-published through Creative Commons. I adjusted my review.

Sounds like a lot of fun. I like the sound of mathematically-enhanced fighting. Reminds me of Robert Downey Jr.’s Sherlock Holmes movies and his fight scenes. 😀

Oh yeah! I remember that!
A very good character. There’s several other in the series that will probably be released after this one.
