The Arachne Protocol. 1, #1

Jo Kern's world collapses when her estranged father dies, revealing the truth she never wanted to face: her mother's death fifteen years ago wasn't an accident-it was murder. And the revolutionary medical research her father protected is worth killing for. The Arachne Protocol, based on spider regeneration, could heal catastrophic injuries and save millions of lives. But Dr. Catherine Vance, CEO of BioMedica Pharmaceuticals, and General James Cortland of DARPA have other plans.
For fifteen years, they've murdered anyone who threatened to expose their conspiracy: suppress civilian access to protect pharmaceutical profits while weaponizing the Protocol for military use. When Jo's investigation puts her family in the crosshairs-including her brother's newborn daughter-she makes a desperate choice: undergo the Protocol herself. Six days later, she walks into a congressional hearing on regenerated legs, living proof of what her parents died to protect.
But Vance and Cortland won't go down without a fight. The confrontation in an abandoned warehouse leaves Jo critically wounded from shrapnel that destroys the leg she just healed and she must survive a second experimental treatment-the first person ever to receive multiple doses-proving the Protocol works while battling complications that could kill her. Perfect for fans of Blake Crouch's UPGRADE and Alex Michaelides' THE SILENT PATIENT, THE ARACHNE PROTOCOL is a fast-paced medical thriller about family loyalty, corporate greed, and the courage to finish what others started-no matter the cost.
