More about the book

"On a backward world with six moons, an alert spy reports on the doings of one Dr. Vosill, who has mysteriously become the personal physician to the king despite being a foreigner and, even more unthinkably, a woman. ... Elsewhere, in another palace across the mountains, a man named DeWar serves as chief bodyguard to the protector General of Tassasen."--Jacket.
