Following the colossal battle against the Empire's warriors on the Burning Plains, Eragon and his dragon, Saphira, have narrowly escaped with their lives. Still, there is more adventure at hand for the Rider and his dragon, as Eragon finds himself bound by a tangle of promises he may not be able to keep.
