In his second full-length poetry book, On Razor-Thin Tires, Charles Halsted explores connections with parents and siblings, friends and neighbors, birds and nature, and reactions to the world he lives in. Central to his life is his choice of a career in medicine, an inspiration for poems on becoming and being a physician. Through the eighty poems in in this book, Charles Halsted reflects on each stage of life, from childhood to adulthood to aging.
