The Duke of Uranium(2002)

John Barnes

Living on a 36th-century space station, 18-year-old Jak Jinnaka's seemingly normal life turns when strangers viciously attack him and kidnap his girlfriend, Sesh. When Jak learns Sesh is actually a princess from a distant world, and that he has been groomed from birth to be a secret agent, he sets out to free Sesh from her captor, the mysterious Duke of Uranium--and discovers a world he never knew existed.
