Letters to my Angel is the diary of a special boy named Or, who was diagnosed with Sensory Modulation Disorder (SMD) at age 3. Sensory Modulation Disorder (SMD) is an imbalance of the sensory system that results in a weakened or amplified response to stimulation. This affects the individual's ability to appropriately respond and cope with day-to-day life. Or is an eight-year-old boy who writes letters to his imaginary angel to help him live with the disorder. Through these letters, Or searches for coping strategies to achieve sensory balance within the constraints imposed by his condition. Or records his life from age two and a half, when he began to talk and became aware of his interactions with the world around him. In this moving diary, Or returns to his life experiences in his domestic and school environments, while describing the path he had to travel as a child with SMD. His observations are a fascinating combination of rationalist, emotional and spiritual elements. The author is a philosopher and educator, and has been involved in both of these worlds for thirty years. Illustrated by artist Noga Sinai, the book includes an index and notes that assist the reader in gaining a comprehensive understanding of Or's experiences.
