Klepsydra
Read full descriptionHide full description
Klepsydra is the very first novel with original soundtrack. Put your headphones on and, while reading, you will be immersed in a musical environment composed and performed for that novel only. You will then discover a new way of reading and you will get deep into a "page turner" fascinating historical thriller novel. Here is the pitch : "21 December 1988, 1907 hrs Three days before Christmas, an American airliner of the Panam crashes in the heart of the village of Lockerbie, in the south of Scotland, making 270 victims. After the stupor, opens the largest police investigation ever organized on the British territory. While Scotland Yard and the FBI are working together to identify the perpetrators of the tragedy, investigators are afraid of a new attack. A real race against time begins."
