When Dylan wakes up after her train has crashed, she thinks she has survived unscathed. But she couldn't be more mistaken: the bleak landscape around her isn't Scotland, it's a wasteland - a terrain somehow shaped by her own feelings and fears, a border to whatever awaits her in the afterlife. And the stranger sitting by the train track isn't an ordinary teenage boy. Tristan is a Ferryman, tasked with guiding Dylan's soul safely across the treacherous landscape, a journey he has made a thousand times before. Only this time, something's different. The crossing, as ever, is perilous, with ravenous wraiths hounding the two at each day's end, hungry for Dylan's soul. But as Dylan focuses her strength on survival, with Tristan as protector, challenger and confidant, she begins to wonder where she is truly meant to be - and what she must risk to get there.
