Shroud of shadow

"In the Age of Inquisition, there is no place for magic. Nor is there a role for Elves, the keepers of enchantments. Natil was the last of her people, but in this time when the Church sentenced guilty and innocent alike to torture, what place was there for one such as she?"@en
"In the third book of the Strand Novels, set nearly one hundred years after the conclusion of Maze of Moonlight , one Elf is the last hope for the future of her entire race The magic of the Elves is fading. The Elves themselves have been viciously persecuted by the humans they once strove to protect. Natil, an elven harper, after traveling the globe in an unsuccessful search for others of her kind, finds herself in the employ of a merchant of Adria. Accompanying her is Omelda, a runaway nun haunted and abused by the voices in her mind. But when the abuse turns violently and lethally physical, Natil and Omelda go on the run, only to fall into the clutches of the Inquisition. Natil, visited again and again by visions of a future reawakening of the immortal blood, must regain her elven powers, not only to heal Omelda, but to carry on as the last—or perhaps first —of her kind. Shroud of Shadow is the third book of the Strand Novels, which conclude with Strands of Sunlight and are supplemented by the story collection Spires of Spirit ."@en
