Katherine Kurtz
Katherine Kurtz (Katherine Irene Kurtz) is an American fantasy author. She was born 1944. She is best known for the Deryni novels.
Deep within a sea cave, sacred texts of the black arts have been recovered from the corroded hulk of a World War II German submarine. Within these pages lies the power to spawn a new, demonic Third Reich - and make Aryan world conquest a terrifying reality. Now they rest in the hands of the Phurba, a vile dagger cult older than Christianity itself.
Only Adam Sinclair can prevent the deadly blades of the Phurba from piercing the heart of humanity. Only he can quell the darkness that lives in... Dagger Magic.
