Countermeasure. The Neon Pulse Chronicles, #5

In a world where flesh meets code, survival demands more than skill-it demands soul. Cass is a streetwise hacker with a medtech background, caught between her past as the adopted daughter of a cop and her present in the cybernetic underground. Armed with an organic deck grafted to her arm and a library of stealth programs, she prowls the net disguised by common avatars and layered deception. But when a piece of rare neuromorphic tech falls into her hands-damaged, dangerous, and possibly the last clue to her stepfather's unsolved case-Cass must outwit corporate giants like NeoGen Biotech to find the materials needed to repair it.
The deeper she dives, the more the lines blur between memory, identity, and what it means to be truly human. Stefan was raised to believe the world was safe-until conscription dropped him into the blood-soaked soil of Belize. Thrust into war under the Texas Army banner, he discovers that his body has been altered by experimental nanobots, capable of healing him and shielding him from harm. whether he wants them or not.
As he witnesses the horror of battle and the cold reality behind corporate warfare, Stefan's innocence crumbles. Partnered with the no-nonsense soldier Tera, he's forced to confront not just the cruelty of others, but the terrifying cost of the power inside him. Two paths. One future. As Cass and Stefan fight to hold onto their humanity in a world dominated by synthetic control, they edge closer to uncovering a truth neither of them is ready for-one that may change the world forever.
