To Live Again

"Immortality is just a dream, but with the Scheffing process, the extremely wealthy can purchase the next best thing. For an exorbitant fee, the Scheffing Institute will make a copy of your mind's persona, hold it in storage until death, then transplant it into sublayers of the brain of a willing--& paying--host. The result for the host is immediate access to the persona's memories, knowledge, experiences & judgment. For the persona, it means full consciousness & thought-communication with the host, but without physical control of the host's body. When this futuristic tale unfolds, the brilliant, powerful multi-billionaire Paul Kaufmann has been dead for months. Institute administrator Francesco Santoliquido must make the decision of assigning Kaufmann's persona to a compatible host. With a personality as strong as Kaufmann, Santoliquido must be wary of the chance that the persona could take over the host's body--known as "going dybbuk." The only two men strong enough to control Kaufmann's persona are the ones who could benefit from it the most: Paul's nephew & current executor of the Kaufmann empire, Mark Kaufmann--& Mark's primary business rival, John Roditis of Roditis Securities. A secret struggle for possession of Kaufmann's persona takes an unexpected turn when Mark's 16-year-old daughter Risa gets involved" -- Goodreads.
