Nice to read of a young woman heroine who saves the world primarily through her own perseverence and loving nature rather than combat. There is some swordplay combined with an unknown energy. While somewhat along the line of Lewis' Lion/Witch/Wardrobe series, with it's lion-like guardian and a strong ethical value, this has a slightly older heroine and a much different world, with genetically modified beings who are self aware/sentient.
I see many people have tagged this "Vampires". While the Icari do bite their victims on the neck, they are sucking out the soul rather than their blood, and the story is more about the mad power grab of the White Witch.
It is written in a very dreamy-state, where Aeriel ponders things and is never sure where she is going on her lengthy journeying, always on an important mission. She follows her intuition and is true to her heart. She learns to see even the most grortesque and fearsome beings with a loving heart. Somehow helpers come at a crucial moment, or she seems to hear suggestions in her head which guide her response. There are others who are pure evil from whom she escapes or is rescued. While I can't pinpoint any particular dissatisfying aspect which would make me say this is not positive, this book seems foster a dependence on outside influences.
Gave to a Little Free Library: some merit to the book which others may find enjoyable, but not specifically aligned enough with my collecting impulse to keep. ( )

I remember reading this series when I was very little, and being so in love with it that I was unable to stop reading them. Eventually, the books fell apart, but years later I still have two copies of each on hand. ( )

Totally unique. ( )
