Mi'hal'ē is different from all the other analong, not just on the outside, but in ways even she doesn't understand. Born into a world, where no one else looks like her, Mi'hal'ē's ah'sha has forbidden her to go Outside past the fields. But, the key to who she is and who she belongs to might lie far further past the Outside than anyone knows. And if Mi'hal'ē ever does find her truth, can she accept its responsibilities? The book follows the journey of one young análong, as she discovers the truth about family, the price of identity, the power of choice and the requirement of love to save the world. Written as an allegory of childhood mental illness, characters and events in The Book of Moon: An Loúr ihn G'éalach are based on the author's experience as a child and teenager growing up with a mental illness with the intent to help create awareness of the isolation, discrimination and stigma experienced by the mentally ill in their everyday lives.
