Phase Space: Stories from the Manifold and Elsewhere

Graham Vingoe

I love and highly recommend the entire Manifold series- to me it's where Stephen Baxter hit his stride as a writer. This is a collection of stories related to the series, sometimes tangentially other times it features characters from the series. More hits than misses but you probably need to have read the 3 main books first to get the true flavour of a number of the stories. Excellent collection.
