My apologies for not continuing this recently. As it happens I had written up the first two chapters of a sequal (well, a prologue scene and a first proper chapter). Unfortunately my computer went completely kaput. I lost everything, the original draft of 'Broken Bow', and all I had written so far of the second story.
Oh well, pick up the pieces, start again...it'll take a little while, but it's on it's way.
Coming (fairly) soon, 'Starship Enterprise-Strange New World.'
