For the next two days only you can legally download electronic copies of popular sci-fi and fantasy books such as Robin Hobb’s Assassin’s Apprentice and Kim Stanley Robinson’s Red Mars.

Random House sub-site Suvudu has been offering these titles, along with His Majesty’s Dragon by Naomi Novik, Settling Accounts: Return Engagement by Harry Turtledove and Blood Engines by T.A. Pratt for the past few months as a once-only promotion.

However it will end on August 18, so you had better be quick if you want copies. Keeping the Door thanks the generous folks at Suvudu for the copy of His Majesty’s Dragon we downloaded; we haven’t read it yet but plan to read it on our iPhone.

But don’t worry too much if you miss out; there are still a stack of other free e-books up, some from quite famous authors such as Stephen Baxter, whose book Manifold Time is available, Terry Brooks, who has Magic Kingdom for Sale — Sold! up and Michael Moorcock, who has Elric: The Stealer of Souls available.
