Sum is a stunning exploration of funny and unexpected afterlives that have never been considered—each presented as a vignette that offers a lens through which to see ourselves here and now. In one afterlife, you find that God is the size of a microbe and is unaware of your existence. In another, you work as a background character in other people's dreams. Or you may find that the afterlife contains only those people whom you remember. The stories in Sum are rooted in romance, science, and awe: a mixture of death, hope, computers, immortality, love, biology, and desire that cuts through human nature at new and exciting angles.
