The Call of Kerberos — Jonathan Oliver

The world changes for Silus - a simple fisherman from Nurn - when a man on the run from the Final Faith tries to persuade him on an extraordinary voyage. Then an ancient evil bursts from the sea and tries to claim Silus as one of their own. To discover the truth about his legacy Silus must take to the forbidding Twilight seas. There, the truth will forever change his world and threaten existence itself!
