Black Abyss. Volume 2. Among the Snakes

While the monsters from the Underworld ravage Skyland, Konrad commands a squadron of ships at the orders of his uncle, the king. But high status cannot protect him from mistakes and betrayals.
Exhausted by bloody battles and the tyranny of his uncle, Konrad decides to prove his worth to all of Skyland. He embarks on a secret expedition to turn the tide of the battle – before another celestial island ends up in the monster's maw. In this journey, Konrad and his crew face deadly dangers and astonishing discoveries. And to endure them, Konrad must find something more within himself than just courage.
