Dream Boat (A Claudia Seferius Mystery Book 7)

"Kidnapped? What do you mean, the silly cow's been kidnapped?"
Claudia didn't believe for one second that her stepdaughter had been abducted, and she was right. But when Flavia's stupid prank costs a young man his life, this was anything but funny. Frustrated and furious, Claudia turns to the one man who can help - only to find Marcus is under house arrest after a body is found walled up in his house. 
She eventually tracks Flavia to an Egyptian cult in the hills, whose leader bends the members' minds to his own sinister will. But worshipping the Barque of Ra is one thing. When one of the cult members starts to believe he is the incarnation of Seth, brother of Osiris, God of Chaos, the Dark Destroyer himself, the game turns very dangerous indeed.
