The paper version of The Skull Ring just went live at Amazon at $14.95. You can get a signed copy directly from Scott at $9.95 (plus $2 shipping) by ordering through Paypal and he will ship it out as soon as the books arrive (which should be around March 19). The quality is surprisingly good.
The Red Church is also available at Amazon but we probably won't stock it since there are lots of cheap used copies available. If you are interested in a signed copy in trade paperback size (the previous editions were hardcover and mass-market paperback)
