Well, it's up!
The Fourth Dimension: The Vezulian Trilogy is now available for purchase at Smashwords.com. It is currently processing with Amazon.com and should be available there within 24-48 hours. I'll post a link here when it's ready.
As for all other sites, it takes time for Smashwords to distribute to each of those channels, so it may be a couple of weeks before they're available. You can, however, purchase the format required by your specific e-reader directly through Smashwords.com.
Included in The Fourth Dimension: The Vezulian Trilogy
Volume I: Key to the Stars
Volume II: Alliance of Serpents
Volume III: Eye of the Tornado
I'll bring you more links/information as it becomes available! Thanks again for your interest in The Fourth Dimension!
