If you’ve read Doppelganger already, then check out the page on my site for Warrior and Witch, newly updated with all kinds of goodies — including the first chapter of the novel! It’s the revised version of what got printed in the back of the first book, and next week (one week from street date!) I’ll be adding a section from the second chapter.
If you haven’t read Doppelganger already, then please don’t follow either of those links, as they lead to spoilers that make Baby Jesus cry. Go read the first book instead.
