How many lives can a single ride change? Can the butterfly effect take the shape of one big, black horse and his rider, waiting on a petrol station forecourt in the dark of night? Cai Sawyer - accountant, part time publican, heir to an artisan candy business, environmental activist, ex pony racer. Cai is all of these and nothing, with a hole in his soul that has eaten the spirit of the boy he once was. He stumbles through life on autopilot, challenged only by Ariadne, his weird as all hell little sister, until he meets Orwen and her Trakehner Toby under February's full moon. Their chance encounter should have ended with a short but sweet thank-you kiss, but the tides of fortune have other ideas. As ripples become waves, change sweeps not just through Cai's life but through that of a whole host of humans, horses and dogs who are brought together by circumstance and leave as a tribe. Written in the tradition of Iain Banks, if Iain Banks had written horse novels, The Nightrider is a modern retelling of Sleeping Beauty, in which everybody is wide awake.
