My Fearful Symmetry — Denise Verrico

A boy becomes a vampire and fights to become a man. Only the most gifted and beautiful Immortyls are chosen to serve Mother Kali as adepts of the ancient arts... For nineteen-year-old Cedric MacKinnon, the promise of eternal youth and celebrity sounds like a dream come true. It becomes a nightmare when a master vampire plucks the boy from the London streets and spirits him away to India. In the fabled ashram of the adepts of the ancient arts, Cedric undergoes the grueling process of training as a temple dancer and courtesan. With the threat of revolution hanging over court, the chief elder employs the boy he names Shardul in dangerous games of seduction and intrigue. Hated by the chief's mistress and abused by those he entertains, Cedric struggles with visions of a violent destiny that seem to come from Kali herself. The stakes are heightened when the rebel leader, Loki, is brought to India for trial and Cedric is forced to choose between the protection and patronage of a powerful elder and his love for a beautiful female adept.
