About This Book
The salty spray of the sea stings Thomas Spyre's face as the Elizabeth Bonaventure cuts through the waves. The creak of the wooden deck and the sharp cries of seagulls fill the air, but beneath it all, a storm is brewing—not just in the sky, but in Thomas’s heart. When his master dies suddenly, Thomas must step up as ship’s surgeon and fight to protect his ship and crew.
