With this epic tale of altered histories and different earths, a universe where Alexander’s empire prompted a different past, a world where strange alien ‘eyes’ gaze upon a fractured reality, a time when man is looking to colonise the red planet Arthur C Clarke and Stephen Baxter scale new heights of ambition and sheer story telling brio.

This is classic SF adventure from two of the biggest names in the genre. A heady combination of high concept SF, big engineering projects and human drama.
