With the success of Existence, Orbit are relaunching David Brin's earlier books in the UK to accompany the release of the paperback edition of that novel on 1 November.
Also released on 1 November are The Postman and Earth. The Postman is a post-apocalyptic story in which a man chooses to provide hope to the survivors of a nuclear war that the US government still exists and will save them. Forget the horrible Kevin Costner movie (which shares very little in common with the novel beyond the basic premise), The Postman is an enjoyable novel about hope and the morality of lying for the greater good. Earth is Brin's epic SF story about a black hole that appears at the Earth's core and threatens to destroy the planet.
Released on 6 December is Uplift, an omnibus of the Uplift Trilogy, consisting of Sundiver, Startide Rising and The Uplift War. The second and third books in this sequence are widely regarded as Brin's best novels, winning him multiple awards.
An omnibus of the Uplift Storm Trilogy (Brightness Reef, Infinity's Shore and Heaven's Reach), entitled Exiles, follows on 17 January 2013.
