I just started Avempartha by Michael J. Sullivan. I am in a goodreads group with the authors wife and she posted that it is free for the Nook. It is basically an adult action/adventure/fantasy novel. It is very different and unique so far. It is actually book 2 in a series, but I was assured by his wife that it can be read as a stand alone. I will probably be buying the rest in the series anyway. Here
is the link if anybody is interested.
