PB asked Scott Hawkins:

It's a trivial detail but... I'm going to ask it anyway to satisfy my curiosity. If Carolyn's catalog is to know every other language there is, including the language of animals, why does she still have a difficult time communicating with Michael? Sticking only to her own catalog, can Carolyn learn the language of animals up to a certain depth? Or did I just misunderstand that part of the novel?
