Summerlight, an inside-out world of crystal and vintage light, is the home of the mysterious battle-artiste known as 'The Shadower'. His quest to perfect his stealth suit will bring him into conflict with the invisible and terrifying Keer, cut-throat and ruthless Corp-nation politics, and the enigmatic and benevolent mistress of the ancient, cult society known as the Hive. As darkness descends, only one person can see the paths of future-tense, and walk in such a way as to avoid the annihilation of all sentient life in the galaxy.
