Bone Crossed, it seems like a good time to post the link to the first chapter of Silver Borne. I saw this the other day thanks to a post on Angieville, which also mentioned this would be Samuel's book. I don't normally read chapters online, but I did read this one (partially because I was hoping it would help me decide about my dilemma about whether or not to wait for paperback - no, still undecided). Silver Borne is the fifth book in the Mercy Thompson series and will be released on March 30.
Due to an email from Borders, I also noticed that the first book, Moon Called, is coming to hardcover on March 2. The fourth book was the first one released in hardcover so the first three books had only been available in paperback (unless you include the Science Fiction Book Club version, which contained the first three novels as Preying for Mercy).
