Beth is a spirited woman with mental retardation who spends nearly every day riding the buses in her Pennsylvania city. The drivers, a lively group, are her mentors; her fellow passengers are her community. Beth, who lives independently and has a boyfriend, is a joyful, endearing, and feisty individual. Her single sister, Rachel, a writer and professor, masks her emotional isolation and loneliness behind her hyperbusy schedule. When Beth asks Rachel to accompany her on the buses for one year, they take a transcendent journey that changes Rachel's life in incredible ways, leads her to accept her sister at long last-and teaches her to slow down and enjoy the ride.Simon, Rachel is the author of 'Riding the Bus With My Sister A True Life Journey', published 2003 under ISBN 9780452284555 and ISBN 0452284554.
