An early work by Asher, Africa Zero comprises two novellas set in a distant future where the Collector, a lone cyborg with attitude, wages war on an army of religious fanatics. A nice brisk read, this book has the Asher trademarks of high octane action and plenty of big explosions. Fans of his Polity series will recognise the reptilian sauramen as forerunners of the dracomen in later books, but these prototypes are more entertaining. Few science fiction stories are ever set in Africa, let alone feature mammoths, glaciation, vampires and giant crocodiles as well, so this is one to remember.
