Both works are journeys. The protagonists did not go on their adventures because they needed, or in face of an imminent danger: they simply wanted to do it. In their journeys, they find other people, they learn, each step at a time as they draw closer to their objectives, and in this, they find meaning.
Also, both of them are very well written with interesting worlds and concepts, and pass beautifully emotional messages.
