With over 30,000 paid books on the iBookstore, UK-based author Adrian Dawson has stormed straight into the top ten with his debut novel, Codex. The novel was placed as high as Number 6 in total UK sales in the ebookâ€™s first week on sale through Appleâ€™s iBookstore and consistently maintains its position within the Top Ten. Adrianâ€™s novel follows the struggles of Chess Grandmaster turned IT entrepreneur and philanthropist Jack Bernstein as he battles to find the truth about his daughterâ€™s death. Drawn into a global game of chess in which he has been an unwitting pawn for over a decade, a complex web of deceit and betrayal unravels to reveal that all is not as it would appear. Fast paced and with a fierce array of coded clues delivered throughout, the novel is clearly finding favour with a large number of UK iPad and iPhone readers. Joanne Sayer, owner of Last Passage Publishing who represent Adrian's work revealed; â€œThis is fantastic news for Adrian, who recently attended Book Expo America in New York to publicise Codex prior to its publication in print in November. Our decision to release Codex in eBook format prior to release in print, was really about testing the market for Adrianâ€™s work and eBook sales in general, but with the iBookstore it has proven to be an even greater success than we anticipated. Pricing Codex at Â£2.49 will no doubt have played a part in its meteoric rise through the charts, where it is currently sitting at No 2 in the â€œMysteries and Thrillersâ€ section having been kept from the top spot only by Peter James, whose Â£1.99 Short Story â€œThe Perfect Murderâ€ has held the No 1 spot in Mysteries and Thrillers since mid June.â€ Codex is available in all ebook formats and will be available in print from 4 November. At the time of writing, the novel holds the #6 slot on the UK iBookstore.
