It’s been four years since seventeen-year-old Mitchell Johnson was hit by a bus and inexplicably ended up in the Underworld. Hell is miserable, but Mitchell knows things could be worse.
After all, he has the coveted job of The Devil’s intern–plus three close friends who keep him from dwelling too much on his untimely demise. Still, he’d rather be living. So when Mitchell discovers that his boss is in possession of a legendary time-travel mechanism called a Viciseometer, he starts forming a plan.
With a device like that, Mitchell realises, he could escape Hell, revisit his death, and prevent it altogether. Getting his hands on the device turns out to be easy. But preventing his friends from accompanying him–and protecting them from whatever it is that’s stalking them through time–is going to be impossible.
