Quote from : Beta Book

I know she is scared of this simple task even if the fear is something she can't—or won't— acknowledge. Fear, perhaps, is not based on the chemical component of adrenaline alone. It acts also on inexperience, or venturing into the unknown, even if that unknown is as uncomplicated a thing as a swimming pool. At least, the pool feels uncomplicated to me, a natural extension of myself. To Xanthe, who has never been in one, it might seem like the great wild unknown.
