Elf Stone of the Neyna. Lost Xentu, #1

Called by a strange and thrumming voice that cannot be shut out, Yanda deserts everything--her small daughter, her post as surgeon, her life on Planet Alland. Pulled across the universe, her ship is waylaid by the dark mage, Kridenit ("Krid"), who collects those with talents. Though she's had the ability to see through, into bodies, past walls, since childhood, she's never known the extent of her powers.
Now, owned by Krid and needed by the Elves, she must find a way out of the Terlond Citadel to help prevent Krid from obtaining the great Elf Stone of the Neyna and fulfilling his nefarious plans for them all.
