I am so sorry to hear of your troubles. Will you let us know if they are are revised or simply re-released? Torquere is where I first found you.
I'm guessing this is why when I went to buy book 4 from the Hammer series today all of them were unavailable. I am so sorry you are having this trouble. I read a few out of order while I was trying to find book 1. So I will reread them while waiting to find out what happens next with Billy and Montana.
