Who Cares? (Sequel to Who Knows?)
After dying for a second time, Huskie Majine wakes up in a hospital to the words "Simulation complete." She finds out that the life that she knew, even her name, was just a lie, a simulation experiment in the future. She remembers nothing of her real life, just the one in the simulation.
In truth, there was a huge war going on, and Huskie was a soldier lost in action. She was taken by a doctor for experimentation, and she was stuck in a simulation for five years, though it seemed like a lifetime. So now Huskie's stuck in a world that she doesn't know about, and worse, she's being put back into the war.
