Sixteen thought she had disappeared.
In the frozen Upper Peninsula of Michigan, she lives under her real name, working wind towers, keeping her head down, and pretending the program that made her has finally lost the scent.
Then a historic winter storm hits.
A remote wind farm fails. The grid begins to buckle. Towns go dark. People will freeze if the power does not come back. With roads closing and rescue grounded, Sixteen is handed the impossible job: drive an 80,000-pound rig through fifty-six miles of whiteout, ice, dead roads, and collapsing timber to deliver the equipment needed to stop a regional blackout.
But the storm is only part of what waits for her.
Someone has found her. Someone from the old world. From the labs. From the blood-soaked history she has spent years outrunning.
Now, trapped in a killing blizzard with the clock running out, Sixteen must keep the rig moving, keep the mission alive, and survive whatever came out of the snow to bring her home.
SIXTEEN: SUBZERO is a brutal winter survival thriller in the Sixteen series, a hard road through ice, machinery, memory, and violence.
