The King's Buccaneer (Riftwar Cycle: Krondor's Sons) by Raymond E. Feist

In a world teetering on the edge of chaos, the lives of two brothers, loyal to their kingdom and each other, are forever changed by the tides of adventure. As they set off from the familiar comforts of Krondor, their quest is fraught with peril and the ever-lurking presence of treachery. Directed by an unquenchable thirst for glory and influenced by the weight of their heritage, they find themselves embroiled in the complex relationship between piracy and nobility that defines the realm.

As they navigate through treacherous waters and clash with formidable foes, the brothers must confront not only external dangers but also their own aspirations and moral dilemmas. Bonded by blood yet pushed to their limits, their journey reveals the profound cost of loyalty and ambition in a land where the lines between heroism and villainy blur. Ultimately, their saga becomes a testament to courage, sacrifice, and the indomitable spirit of adventure.
