The novel “The Garden of Rama” by Arthur C. Clarke and Gentry Lee was published for the first time in 1991. It’s the sequel to “Rama II”.

Nicole Des Jardins, Richard Wakefield and Michael O’Toole remained on the enormous alien spaceship called Rama II when it resumed its journey into space leaving the solar system. During the long journey to the Sirius system they have some children but when they arrive they discover that it’s just a relatively brief stop and the mysterious builders have other plans.

A habitat suitable for human beings is built within Rama and the three passengers are asked to record a video to invite Earth to send 2,000 people to build a colony inside it. The terrestrial governments keep the message secret and the settlers think that their mission is to create a new colony on Mars.
