Sailing For Shadow City — Rachael Lucas

Four steps down, turn to the left.Beware the dark prince in the city of shadow.The castle's base holds a prize beyond measure.These words, spoken by a dying man on a wrecked ship, are what starts Sarkin on the longest and most daring adventure in his life. To a young pirate who dreams of a bigger ship and plenty of treasure to go around, it's the best promise that could be given. But after fighting his way through a mystic cult, a sea serpent and a fierce storm, facing the Dark Prince may be more than he asked for.
