All caught up! Now I have a long wait for the next book. Very compelling story, it just makes you keep asking what's going to happen next, what else are they going to find, will they survive long enough to bring back their discoveries? When I just thought that I had a 'good' idea how some things were going to go, A big character twist was thrown at me, one I really didn't expect. Great story telling, can't wait for the next. ( )
