Description
From Goodreads: THEY CALLED HER A WANDERER. Shari Cooper is dead, the victim of a murderous attack. She is on the other side, in a place of spirits, an eternal realm of light and love. But she is given a rare offer. To return to Earth without having to be reborn. Into the body of a depressed teenage girl. A transfer of souls, they call it. Shari is given a chance to be a Wanderer, and to do a great service for humanity. It is an offer she gladly accepts. Then she is back, in a human body. Yet she does not remember being Shari Cooper. At first she recalls nothing of the afterlife. Perhaps it is just as well. Not everybody on Earth welcomes Wanderers. Of the few who know of their existence, some want them dead. And others, the truly evil ones, wish them much worse than that. After her murder, Shari returns from the other side into the body of another eighteen-year-old teenager to keep the person responsible for her own death from killing again.
