In the deadliest game of survival, trust is a weapon—and betrayal is a death sentence.

Andrea McBane has spent months in the Arctic wilderness, hiding from the world that betrayed her. But when a mysterious message promises revenge against the ruthless Axis Corporation, Andrea is forced back into the fight of her life. Axis didn’t just ruin her—they destroyed everyone she cared about. Now, she’s coming for them.

Her mission: infiltrate the Arctic Vault, Axis’s impenetrable fortress of ice and steel, where five hundred million dollars and deadly secrets are buried deep beneath layers of cutting-edge defenses. With a team of misfits—a brash drone pilot, a shadowy hacker, a fearless saboteur, and a warrior haunted by his own demons—Andrea must face an adaptive AI that learns her every move, relentless drones, and the brutal cold that shows no mercy.

The plan is suicide. The stakes couldn’t be higher. But failure isn’t an option. As danger escalates and loyalties are tested, Andrea must confront not only her enemies but the ghosts of her past. Will she destroy Axis, or will they bury her in the frozen abyss?

Under Siege is a heart-stopping thrill ride, bursting with explosive action, relentless twists, and a heroine who refuses to back down. The Arctic is unforgiving—so is Andrea McBane. Prepare to be hooked from the first page to the last.
