Firebreak by Nicole Kornher-Stace

One young woman faces down an all-powerful corporation in this "profound...resonant" (NPR), all-too-near future science fiction debut that reads like a refreshing take on Ready Player One, with a heavy dose of Black Mirror.
Ready Player One meets Cyperpunk 2077 in this eerily familiar future.

"Twenty minutes to power curfew, and my kill counter's stalled at eight hundred eighty-seven while I've been standing here like an idiot. My health bar is flashing ominously, but I'm down to four heal patches, and I have to be smart."

New Liberty City, 2134.

Two corporations have replaced the US, splitting the country's remaining forty-five states (five have been submerged under the ocean) between them: Stellaxis Innovations and Greenleaf. There are nine supercities within the continental US, and New Liberty City is the only amalgamated city split between the two megacorps, and thus at a perpetual state of civil war as the feeds broadcast the atrocities committed by each side.

Here, Mallory streams Stellaxis's wargame, SecOps on BestLife, spending more time jacked in than in the world just to eke out a hardscrabble living from tips. When a chance encounter with one of the game's rare super-soldiers leads to a side job for Mal—looking to link an actual missing girl to one of the SecOps characters. Mal's sudden burst in online fame rivals her deepening fear of what she is uncovering about BestLife's developer, and puts her in the kind of danger she's only experienced through her avatar.

Author Kornher-Stace's adult science fiction debut— Firebreak—is a "fight song in praise of fierce friendship and the strength to endure" (Amal El-Mohtar, Hugo and Nebula Award–winning author of This Is How You Lose the Time War) loaded with ambitious challenges and a city to save.
