Luke Jackson's lively collection of illustrated poetry allows vivid insights into the internal world of people on the autism spectrum. With a focus on the adolescent years - perhaps the most challenging time for anyone with Asperger Syndrome (AS) - 16-year-old Luke considers issues such as unrequited love, the pursuit of happiness and finding calm amid the often overwhelming confusion and frustration that accompanies AS. ''Crystalline Lifetime'' offers a poignant impression of life with Asperger Syndrome and will prove an illuminating read for anyone hoping to gain an understanding of Autism Spectrum Disorders (ASDs), and a source of encouragement to readers living with ASDs.
