Like all of L'Engle's books, the power of love is again a force to be reckoned with as it helps save several characters—not just Charles Wallace but also Meg and a farandola named Sporos. Meg learns to see beyond superficial impressions, and appreciate and embrace inner beauty and strength. Much of the communication between characters in this book involves a process called "kything". This process is similar to telepathy and empathic abilities combined. Meg also learns that she is a Namer. Namers work in the universe to love and Name parts of Creation, and help them to be themselves. This is the exact opposite of what Echthroi do in their Xing or unNaming.
