The Sorceress of Qar (Qanar series, Book 2)

Ted White again takes us to the strange, paradoxical world of Qanar, where a weird, age-old magic exists as everyday reality, side by side with the remnants of an equally ancient but less understood science. The alien "Others" are making a new bid to take over the entire planet..and only the noble Elron stands against them. But not entirely alone after he meets the beautiful Shannara, and she adds her limited psionic powers to his great strength to vanquish the enemy. Together they share an astounding Odyssey--through unpredictable matter transmitters and over treacherous terrain--to reach a hair-raising climax...in this great sequel to Phoenix Prime !
