GAEA Series at Audible.com

GAEA has been wired for sound. Yes that means that TITAN, WIZARD and DEMON are now audio books. Also making the transition to audio are THE OPHIUCHI HOTLINE, THE PERSISTENCE OF VISION and PRESS ENTER.

Some of Robert Sawyer's books can be found there as well. Sawyer's FLASHFORWARD has been optioned for an ABC series pilot. Stay tuned...

Some other authors of note that have audio books from the same site:
Philip K. Dick and Larry Niven.

All these are at Audible.com. It looks to be an iTunes clone MP3 download subscription site. I haven't tried it yet, but now that Varley is available, I may have to.
