Treason's Shore (Inda Series #4)

Only Inda's fame is strong enough to inspire all the squabbling kingdoms to unite and raise a mighty force to protect the strait and repel the Venn. King Evred has also ordered Inda to take over the strait once the battle is won, but Inda, a former pirate, knows that this is a very bad idea. Now Inda must choose between obeying his liege or committing treason.
