If you are a fan of Peter David and have a Kindle (or Nook I suppose), you can not let this pass you up.
This eBook is $2.99 at Amazon (I am sure B&N also have it for the Nook) and I have been reading, and enjoying, this for days. It is one of the best values I have ever seen as far as price and story. Incredible.
They also have it in paper form, I think, but not for this price. This book was the reason I finally gave in and got a Kindle Touch and it has been worth every penny of it. Great story.
Check into it. Thank me later. (I have figured out 6 ... I think ... of the 12 creatures from Earths Mythology, but some I just can't get ... yet)
EDIT - Forgot Amazon link to book.
