The Lucas Davenport and Virgil Flowers don't seem to be available Kindle (at least not for Australians). However I will pencil them in as possibilities.
I will probably try a Kathy Reich's book after I have read the mystery books I already have.
I looked up the Dresden Files and it is more expensive to buy them for the Kindle than to buy as paperback. I will probably buy the paperback (as I do not like spending more than $9.99 for a Kindle book).
