Desde que eu não acho que Katie está voltando, ela percebeu (e postou em sua pergunta) que a série era Remanescentes de KA Applegate.
Do resumo da Wikipedia da série:
It is the story of what happens to the survivors of a desperate mission to save a handful of human beings after an asteroid collides with the Earth. Eighty people are placed aboard a converted space shuttle using untested "quack" hibernation technology and fired blindly into space hours before all life on Earth is obliterated by a large asteroid called The Rock. They are then picked up by a large, sentient space craft of monumental proportions known as 'Mother' which is inhabited by various races. 'Mother' can manipulate the physical environment within the craft's limits and often does so. Only a few people placed in stasis actually were alive and capable of being reanimated when they reached 'Mother'.
