The Kindle edition of Perilous Waif is now available for pre-orders on Amazon, with a scheduled release date of Feb 1. I'm currently doing the formatting work to set up a paperback edition, which should end up being available by then as well. I'll be interested to see what the relative sales of the two editions look like - I keep seeing claims that the Kindle sales market is bigger than the print market these days, but it's hard to know for sure.
For those of you who prefer audiobooks, production on the audio version of Perilous Waif has started. The producer is hoping to have it out around the end of February, assuming all goes well. We're going to be using a different narrator than for the Daniel Black books, so let me know what you think of her.
