This Audiofy audiobook chip packs John Bolen's full 4.5 hour reading of 'The Underground City' on a tiny memory card. A single Audiofy audiobook chip, hardly larger than a stamp, holds a complete digital audiobook, and saves the last listening position automatically, unlike CDs. With an SD memory card slot or low cost adapter like those for digital cameras this Audiofy audiobook chip can be played on Microsoft Windows and Apple Macintosh desktop computers or laptops (Microsoft Windows XP/2000/Me/98, or Apple Mac OS X 10.3.9 and above) or transferred to Apple iPod media players. Audiobook chips also move seamlessly to most Palm OS and Pocket PC handheld PDAs with SD expansion slots, as well as Treo and Windows Mobile 'smartphones' (Palm OS 5.2 or Windows Mobile 2002 and above)... How can humans survive and prosper 1500 feet below the earth's surface? Jules Verne successfully weaves a dark, yet magnificent story into this equally dark world. The story takes place in a revived and now prosperous coal mine. Amazingly, life in the mine has everything that one desires, including a lake, fish and attractive homes. Yet there lurks an evil presence. Unexplainable, malicious, and life threatening occurrences begin. But why? The evil force could destroy the underground world and everyone in it!
