I second many of Kate's recs (the rest I snaffle for my aubible queue...)

Did you enjoy To Say Nothing of the Dog? It's my favorite Willis, quite light-hearted romance in Victorian England with time traveling historians, and many light-hearted moments. The reader is excellent and it's nice and long.

I'm a big fan of Audible, because it's easy and cheap (I think it's twenty bucks a month for two new books, even if they normally cost a fortune). They have a huge selection.

I can't follow Austen before going to bed. I get lost. lol
