If you’re interested, there should be signed copies of COLD STEEL (and some backlist) at Powells (Portland), Mysterious Galaxy (San Diego), and University Bookstore (Seattle). Borderlands (San Francisco) has some backlist but they sold out of Cold Steel at the signing.
I encourage you to support indie bookstores if you can. Any of these stores can take your order for a signed copy and ship the book to you. They all host wonderful events and I thank them for hosting me and my co-eventers (Katharine Kerr, Andy Duncan, and Lilith Saintcrow).
