Memory Lane is now on sale, and has been via Smashwords since January 1st. I was notified about Premium Distribution earlier today, so it should be making its way to Barnes & Noble, iTunes, Kobo and the like soon.
It's also available on Amazon, and Lulu. I will be trying to open up an account on Drivethrufiction this weekend, but since I'm in the midst of a cold, we'll have to see.
I also have to re-do the covers for books one and two, to match the format of book three's cover. The print version will be forthcoming, when I format the cover correctly.
