With no passion left in life, he drowned himself in drugs, alcohol, and smoke until he eventually died. Then, a different John Carter took over his body. After absorbing the original owner’s memories, he discovered just how many terrible things had been done.

The kind of life he had never been able to achieve in his previous world. Then, a ding sounded.
