Curtis MscKinnon is an intemperate, naïve fool. Sure of his invulnerability as an American expatriate, he comes to Borneo to play at being disreputable. His illusions and charm make him a dangerous man: soon enough, he is in trouble and forced to hide in the jungles of Kalimantan.
He discovers a drug once used to the Punan Dayak, a lost race remembered as 'the dream wanderers'. Seribu aso does not, however, alter the perceptions of only the user. It changes the concrete reality of the land itself. MacKinnon has awoken the spirits of Kalimantan, the guardians of an unspoilt land. And he has no idea how powerful they are...
With its echoes of Altered States and Heart of Darkness, Kalimantan has all the enthralling dark magic and superb story-telling that have made Lucius Shepard one of the most acclaimed fantasists today.
