I have not listened to many books on tape. One I really enjoyed was Frank McCourt reading his own "Angela's Ashes", unabridged. It was great in print, too, but didn't have that Irish lilt.
It was kind of funny because not long after listening to the CDs my two oldest friends and their two teenaged sons went on a driving trip to Florida and I gave it to them for the drive. Phil has a wicked gift for mimicry and said by the end of the first day they were all speaking with Irish accents.
