Island of the Unclaimed (Dark Sails Series)

Sybil never imagined leaving her home in London. It was a luxury she could never afford. Her entire life was spent scraping the bottom of the barrel, sneaking scraps and making do with what little money her brother Walter could smuggle back to them from Nassau.

But as time passes and the last delivery from her brother becomes more distant, she soon realizes that she might finally be on her own. Left with nothing but a heading and a broken compass, she ventures into unknown waters.

While the seas are rough, her journey becomes even rougher as she joins a pirate crew. Desperately tracing her brother's footsteps, she finds herself hurtling towards the same fate. Her last hope lies in unearthing her family secrets and making it to her brother's last known location, a cursed island in the middle of the ocean.
