Query: Deus Ex Machina of doom

Okay, it's almost a good idea, except that it doesn't make any sense, and what might have been a moderately interesting premise is destroyed byt an embarassingly poor ending. In fact, it's the worst ending of any book I've read in a long long time. It makes Star Trek V look like great art. It's nonsensical and even somewhat insulting. It's just dumb. Do yourself a favor and skip this one. Go reread "The Forever War" again or something.
