When my husband and I are in the car together, I read to him. I'm sort of like the audio book! While I'm more apt to read a 'chick book' and he's into Civil War history, finding a book we both enjoy is a bit more difficult.
We happened upon a series of books by Charles Todd, a pseudonym for a mother/son collaboration who write wonderful 'who-done-it' books set in post WW I England, an era of history neither of us knew much about.
Ian Rutledge, a detective with Scotland Yard, has returned from the awful trenches of this war with shell-shock he tries to hide, and is trying to get his life back together by taking projects no one else wants. The descriptions of the villages in the English countryside, the memories and nightmares of the bloody battles and the ghosts who haunt Rutledges's head all add to the excellent writing of these clever books. We're reading our 5th Ian Rutledge book at the moment!
I highly recommend "A Test of Wills" the first of the series of Ian Rutledge books.
