The idea of Dr Catherine Halsey going to halo is intersting, but a couple of thoughts. (Dont worry im not running down your prolouge, its bloody good so it doesnt deserve to be - but still heres a few thoughts) -Okay we left Dr Halsey staring at a halo.....but which halo? the remains of the first?? .....delta halo?? or a completely new one?? -Because the 3 chapters are unofficial it may not happen in the next book....so what do other ppl think the good Doctor is up to?.....remember they are not neccessarily going to halo. -Also the MC has to go back for cortana.....if only she was human..the MC would pull for sure! lol
