A powerful sorcerer, traveling onboard a private yacht, sailing to an unknown destination. Stannis, the master of magic. With him he has brought Heather Taylor and her son Noah. Over these past weeks, Heather has struggled to learn magical incantations in strange languages. She must become a mistress of magic as quickly as possible if she is to save the Bishop sisters, Melissa and Rachel, who have been encased in magical sarcophagi to protect them from Tom Taylor's evil spells. 

They will reunite in Paris with old friends Sterling, Alexandria, and Achilles and together brave the famous Parisian catacombs and the dragon who guards ancient magic.

A battle between good and evil will be fought. And this time not even the psychic Sterlin knows the outcome.
