The Rig by Roger Levy

On a desert planet, two boys meet, sparking a friendship that will change human society forever.
On the windswept world of Bleak, a string of murders lead a writer to a story with unbelievable ramifications.
One man survives the vicious attacks, but is left with a morbid fascination with death; the perfect candidate for the perilous job of working on a rig.
Welcome to the System. Here the concept of a god has been abandoned, and a new faith pervades: AfterLife, a social media platform that allows subscribers a chance at resurrection, based on the votes of other users.
So many Lives, forever interlinked, and one structure at the centre of it all: the rig.
