Can't recall off the top of my head on teh Noir series, but I know you get the ebook free if you buy Vulcan's Kittens or
The Eternity Symbiote.
First of all, when I started writing Vulcan's Kittens, which is my first published novel (I had about half of
The Eternity Symbiote written prior to it, although it would be published later), I wasn't trying to make money.
Also, had I gone with the 5 × 8 size you see on
the Eternity Symbiote, they would have been as thick as it is.
