I can second the Hardcore History podcast if you're into history.
For fiction, it's hard to made a recommendation without any idea of what you like. But I'll reach back to my days as a book store clerk for my go-to recommendation whenever anyone asked for a 'good read':
Pillars of the Earth by Ken Follett
It's a novel about the construction of a medieval cathedral, rich with heroes, villains, betrayals, etc. It's not great literature by any stretch of the imagination, but it's a cracking good story.
