Heart-breaking, uplifting and full of adventure, The Long Ride Home is the long-awaited sequel to the international bestseller The Horse Boy.

Rowan came back from the shamans in Mongolia a changed boy. The three most debilitating effects of his autism - his incontinence, his endless tantruming, and his inability to make friends - were gone.

But a year almost to the day since Rowan's improvement he started regressing: the accidents and tantrums reappeared, terrifying his father Rupert. Something had to be done.

Father and son embarked on a new quest, journeying from the bushmen of Namibia to the coastal rainforests of Queensland, Australia and finally to the Navajo reservations of the American southwest, where Rowan was transformed - they had begun the Long Ride Home.
