Geoffrey Wilson was born in South Africa, grew up in New Zealand and then backpacked around the world before eventually settling in the United Kingdom.
He studied Hinduism and Buddhism at the University of Canterbury, New Zealand, and has been fascinated by India since travelling there in the early 1990s.

It is 1852. The Indian empire of Rajthana has ruled Europe for more than a hundred years. With their vast armies, steam-and-sorcery technology and mastery of the mysterious power of sattva, the Rajthanans appear invincible. But a bloody rebellion has broken out in a remote corner of the empire, in a poor and backward region known as England. At first Jack Casey, retired soldier, wants nothing to do with the uprising, but then he learns his daughter, Elizabeth, is due to be hanged for helping the rebels. The Rajthanans offer to spare her, but only if Jack hunts down and captures his best friend and former army comrade, who is now a rebel leader. Jack is torn between saving his daughter and protecting his friend. And he struggles just to stay alive as the rebellion pushes England into all-out war.
