The final volume in Baudino's powerful trilogy tells of a young woman who's transported to an alternate realm to defend its people. Suzanne sets out to stop the flying things that are destroying Gryylth, even though Suzanne was responsible for bringing the fighter jets to Gryylth in the first place.

The third and final book in Baudino's "Dragonsword" saga, this is certainly a finale worth the pain and tears (oh, wonderful tears!) it took to get here! Unforgettable characters in a fantasy setting that is as believable as one's sanity... *grins*
