The Paris Affair has been available from the publisher's website since Wednesday. From there, the "buy" links will download straight onto your Kindle or Nook (or allow you to save a file for loading separately, for folks like me who have non-wifi enabled e-reader...).
But as of this morning, my book is also for sale directly on Amazon's website! Discoverability is a good thing! The image below is the buy link.
B&N should be coming soon.
