Explore an Alien Treasure Vault

It is June 1942 and Section M receives intelligence from a trusted source concerning the emergency evacuation of a weather observation facility (WOF) on Olivia Island, an otherwise insignificant rock 650 miles south east of the North Pole.

A coded message indicates that a U-boat recently extracted the entire complement of the German weather observation facility there for immediate return to the Fatherland. Section M has long believed this base to be a covert Black Sun operation, and its codename, “Die Schatzkammer” or “Treasure Vault”, would indicate that something of significant value remains there.

Now M are in a race against time to reach the station and uncover its secrets before the Germans can reoccupy the base. Agents are dispatched aboard the Njord’s Bounty, a friendly Norwegian vessel to make the journey, make a tactical assessment, and recover any assets of value.

But when they land on Olivia Island, many unknown perils await them. Can the agents survive its harsh weather conditions, probe the secrets and mysteries of the weather observation station, and with German occult forces apparently closing in, discover the truth about what lies in the enigmatic treasure vault at its heart?

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
