Houdini & Lovecraft: The Ghost Writer by Ron Wilkerson is now available as a paperback. The book was originally released only as an eBook.
According to the author's official website, the fictional book is a novelization of his own feature screenplay that finds Houdini and H.P. Lovecraft trapped in a mansion under attack by deadly paranormal forces.
The book is listed as "Volume 1", so hopefully this means we'll get more adventures of Houdini and Lovecraft.
