EDIT: Well, I had posted it (thank you, advancing senility), but there are details in this post that weren't in the first one, so it's not a total loss.
Grand Central Arena has a publication date of April 27th, 2010; it'll be a paperback, so hopefully there'll be lots of people buying. I'll be working on doing some publicity of my own.
And Threshold, sequel to Boundary, will be released about one month after that (June). That will be a hardcover, of course, as it will also have the much weightier name of Eric Flint alongside mine on the cover.
