Afterlife

Kalden Nicholas, a man of science, has lost all he loved on Earth, but the pull of space and new discoveries drives him on a one-way mission to the far reaches of the universe.
Landing on a mysterious planet, his perceptions of life, death and beyond are challenged and tested in ways he could never have imagined. Finding renewed purpose, he returns to Earth where he learns that faith cannot be proven, and one person can make a difference.

After all, Earth is just a training ground for the Afterlife.
