Equal Rites, Terry Pratchett
The third book in the Discworld series, this time it was an abridged version (2 hours, 54 minutes) narrated by Tony Robinson - which made the listening great, but it would have been nice if it had have been the entire book as Robinson does such a great job.
Right before the wise old wizard Drum Billet died, he passed on his magical staff of power to the newborn eighth son of an eighth son. Unfortunately, Drum Billet never bothered to check the gender of the newborn baby, and it turns out it was a girl. Now his chauvinistic colleagues are forced to deal with a young girl who has all the qualifications to join their all-male profession.
Terry Pratchett's third Discworld novel, Equal Rites, asks many provocative questions about magic, where it goes, where it comes from, and why.
