The Fifth Line: A Novella

Following the passing of his grandfather, Trevor Graves is devastated. In the wake of his trauma, he is given an important task: to go to the family's cellphone provider and cancel his grandfather's old line. He does this and, to keep his current discounted plan, he adds his girlfriend on. As he does his best to navigate his new reality without his grandfather, Trevor starts to revive phone calls from the very phone he thought he had disconnected. Is it just the equivalent of post-mortem spasms or is his grandfather trying to contact him from beyond the grave with one final message?
