Stormchild (The Thrillers #4)

Tragedy has decimated Tim Blackburn's safe and comfortable existence. Having already lost a son in a terrorist attack, he must now cope with the death of his beloved wife, killed in a mysterious explosion at sea. And all that remains of his destroyed family is his missing daughter Nicole, last seen in the company of Caspar von Rellsteb--the mad, charismatic leader of the shadowy environmental activist group called Genesis--who keeps an iron-fisted hold over his fanatically dedicated followers. Determined to free Nicole from the crazed, self-proclaimed "protector of the planet," Tim sets sail aboard the sloop Stormchild, with the beautiful, story-hungry journalist Jackie Potten. But their hunt for the hidden lair of Genesis is leading them into dangerous and terrifying waters--and the darkness that waits for Tim Blackburn on the far side of the world could destroy both his sanity and his soul.
