Sins, Sons, and Siren Songs - The Pirate Hunter Chronicles, #2

A song on the wind. A broken crew to mend. A family's honor to be upheld. Leading a crew is harder than Adi thought. Six months after she took up the mantle of Captain, she finds herself facing more problems than she bargained for: a grieving crew and rumors of sirens attacking local ports. But the crew of the Red Wind might have finally found their match in the underwater warriors of legend. Ravin's life was almost normal, until he finds an assassin lurking outside Master Jermaine's shop and is forced to flee once more.
But Treynair del Mankayl cannot be avoided forever and Ravin has to decide his fate: to run for the rest of his life or stand up and face his greatest nightmare by fighting his father. Only this time, he isn't just trying to save his own life, but that of another as well. When Adi and Ravin's paths cross once more, they are thrown into a storm of myths, assassins, and consequences. But will they be able to weather it with the crew tearing at the seams?
