"There was another reason [she] took her books whenever they went away. They were her home when she was somewhere strange. They were familiar voices, friends that never quarreled with her, clever, powerful friends -- daring and knowledgeable, tried and tested adventurers who had traveled far and wide. Her books cheered her up when she was sad and kept her from being bored."

The principal difference between an adventurer and a suicide is that the adventurer leaves himself a margin of escape (the narrower the margin the greater the adventure), a margin whose width and length may be determined by unknown factors but whose navigation is determined by the measure of the adventurer's nerve and wits. It is exhilarating to live by one's nerves or toward the summit of one's wits.
