Plot summary
The homeworld Acorna has never known was horribly scarred in the brutal attack by the cold-blooded Khleevi, but the Linyaari - the unicorn girl's gentle, spiritual race - live on. Now is the time for healing and rebuilding, for restoring the natural beauty corrupted by the savage insectile oppressors, but Acorna's Linyaari friends and colleagues begin mysteriously disappearing soon after work gets under way, among them her beloved Aari. Her desperate search for answers leads Acorna to a discovery beneath the surface of her people's world - and deep into the realms of limitless space, where the truth of the origin of everything awaits.
