Sorry to be a lttle late in on this Stustaff, but it sounds to me like you might go for an ebook by my own wee publishing house called 'Earthdoom'. It's the SF disaster novel to end all SF disaster novels. A real hoot.
Co-written by old pals John Grant -- he of the many Hugos and Judge Dredd -- and the hilarious Dave Langford who is disappointed that he only has the SECOND largest collection of Hugo awards in the world.
Drop me a line to ntmarrATbewrite.net (use the @ sign, of course) and I'll send it along with another fun offering from John Grant called 'The Hundredfold Problem'.
Anyone else who fancies a good e-read, just pick your titles from
www.bewrite.net and send me a note. It's a pleasure to give these away to new pals at MobileRead -- and a fair swap for all the sound advice we've been so generously given recently by members of the MR community.
Very best. Neil
