Twig Verginix has gained a formidable reputation as the young sky pirate captain who dared to sail over the Edge. But far out in open sky a storm is brewing. In its path lies Sanctaphrax - the great floating city tethered to the land by a massive chain.

Twig has learned of the approaching danger, but a perilous voyage destroys his sky ship, hurling his crew into and beyond the Deepwoods and robbing Twig of his memories. The race against the storm begins, as Twig struggles to reach Sanctaphrax and save its inhabitants before it is too late . . .

Midnight Over Sanctaphrax is the third book of the Twig Saga - second trilogy in The Edge Chronicles, the internationally best-selling fantasy series, which has featured on the UK and the New York Times best-seller lists and sold more than 3 million copies. There are now 13 titles and four trilogies in the series, but each book is a stand-alone adventure, so you can read The Edge Chronicles in any order you choose.
