Isso é provavelmente K.A. Applegates Remanescentes série.
Remnants is a series of science fiction books written by K. A. Applegate between July 2001 and September 2003. 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'.
Sua pista sobre o nome do autor me fez pensar imediatamente em Applegate, e lembrei-me do enredo básico dos livros de tempos anteriores, que era a resposta. Então, foi uma questão de verificar isso por meio de uma rápida pesquisa no Google e observar que a capa também correspondia.
