Not as thrilling and exciting as the first one. If there hadn't been the long tour up and down the silo...it was necessary, I get that. The "quiet" part was important to set the tone and give insight into the life inside the silo - how everyday life (communication, hierarchy, travelling) works there. The story of Jahns and Marnes was very nice, and the all the characters were very believable - and wonderfully introduced. Wondering whom of them I'll encounter later in more detail... :)
