Ashes Don't Die. Shadows of Coal, #2

"A machine does not need a ghost to be haunted. It only needs a memory."Thomas Kane thought he closed the case. The jury convicted the man accused of his mother's murder, but for Thomas, the verdict tastes like ashes. Now a reluctant detective, he knows the real architects of his mother's death-the secretive Genesis Project-are still free. When a series of high-profile government officials and industrial moguls are brutally executed, each scene marked by an escalating, cryptic symbol, Thomas is drawn into the hunt.
Working alongside the weary but principled Detective Cole, Thomas realizes the terrifying truth: the calculated assassinations are being orchestrated by his own father, Michael Kane, a man he believed dead for decades. Michael is eliminating the operatives of the conspiracy he helped create, forcing Thomas onto a path of inescapable moral compromise. As the body count rises and the police machine struggles to maintain control, Thomas must confront his father's impossible choice: join the vigilante war for justice or uphold the corrupted law he swore to serve.
Ashes Don't Die is a relentless political thriller about the cost of truth, the burden of inheritance, and the ultimate futility-or necessity-of fighting a system designed to devour its own opposition.
