Publisher's summary

S. L. Huang's Null Set is the breakout sf thriller for fans of John Scalzi and Greg Rucka.

Math-genius mercenary Cas Russell has decided to Fight Crime(tm). After all, with her extraordinary mathematical ability, she can neuter bombs or out-shoot an army. And the recent outbreak of violence in the world’s cities is Cas’s fault—she’s the one who crushed the organization of telepaths keeping the world’s worst offenders under control.

But Cas’s own power also has a history, one she can’t remember—or control. One that's creeping into her mind and fracturing her sanity...just when she’s gotten herself on the hit list of every crime lord on the West Coast. And her best, only, sociopathic friend. Cas won’t be able to save the world. She might not even be able to save herself.

Critic reviews

"The warning in this atmospheric audiobook, the second in the Cas Russell series, is to be careful what you wish for. Portrayed by skillful narrator Lauren Fortgang, Cas, a math genius and a mercenary, is a mess." -AudioFile

Good story, but annoying

I personally found the scenes (in which Simon and Cass argued about whether he should be allowed to do what he is asking to) to be way too long and too repetitive. I almost stopped listening several times, but I forced myself to go on. Other than that, the story was entertaining.

Something went wrong. Please try again in a few minutes.
