The Fellowship of the Ring (The Lord of the Rings, #1)

by J.R.R. Tolkien

There is a seed of courage hidden (often deeply, it is true) in the heart of the fattest and most timid hobbit, waiting for some final and desperate danger to make it grow. Frodo was neither very fat nor very timid; indeed, though he did not know it, Bilbo (and Gandalf) had thought him the best hobbit in the Shire.
