I’m glad you asked.  It’s called Terra — have I mentioned that?  And it’s the follow-up to The Portal.  Here’s the marketing blurb I wrote for it yesterday:

Larry Barnes thinks he’ll never use the portal again.  The strange device that took him to a parallel universe has disappeared, and he is back living his normal life — until one day a beautiful woman appears and begs for his help.  She tells him that the mysterious preacher he met in his travels is in trouble on another world, and only Larry can save him.  Against his better judgment Larry enters the portal with her, and soon he finds himself in a desperate battle against a secret priesthood that wants to kill the preacher – and Larry.  As he struggles to defeat the priests and return home, Larry begins to sense he may have powers that he never dreamed of, and he begins to understand that his fate is inextricably linked to that of the preacher . . . and the portal.

I don’t like these sorts of blurbs; they seem to suck everything that’s interesting or different out of a book in order to fit it comfortably into its genre.  Maybe I can do better.  Should I bring in the many-worlds interpretation of quantum mechanics?  That would probably help sell some copies, don’t you think?
