The Treasure of Tepatamwa [EPUB ebook] 
The Seventh Book of Dubious Magic

21st Century Maine still has a lot of old world charm. But some echoes of the past are anything but benign. Monsters on land and sea. A band of unlikely but ruthless pirates. A storm at sea, and the real prospect of a watery grave.

In their search for family history and family treasure, John B. Stewart and his beloved Elizabeth, together with old friends and new, find much more than they’d expected — perhaps even more than the wizard’s strange power of dubious magic can contend with.
