It looks like there is 1 used CD for sale on amazon: https://www.amazon.com/DC-Universe-Last-Alan-Grant/dp/1599506483/ref=tmm_abk_swatch_0?_encoding=UTF8&qid=&sr=
You won't find it anywhere else unfortunately.
I would prefer REALMS of Alexonia: Mobilizing Egan
Amazon.com: Komodo (Audible Audio Edition): John Lee Schneider, Robert Wrenlock of Island Audio, Severed Press PTY LTD: Audible Audiobooks
I like the story it has a lot of interesting potential. I laughed when Leo pulled out the Flipper slide. Have you read Repeat by Neal Pollack. I don't have any criticisms (dry pillow tonight). Every writer has their own style and i got a few good laughs. Keep up the good work. I subscribed on google so i don't have to worry about missing a release.
