The Xeelee Sequence is a series of novels and short stories which span several billions of years, describing the future expansion of Mankind, its war with its arch-nemesis (an alien race called the Xeelee), and the Xeelee's own war with dark matter entities called photino birds.

// Note: The chronological order is quite complicated, since books can describe events in different eras. You can find [ a complete timeline]( on Stephen Baxter's website if you prefer to read chronologically instead of by publication order.
