I'm listening to Labyrinth, by Kate Mosse. It's fascinating - bouncing back and forth from modern times (2005) at an archeological dig, to 13th century France. Its a holy grail story. I have to say that the reader for this novel was an inspirational pick, Donada Peters. Excellent.
Down side, this books is something like 16 discs long! Good grief! It's an investment in time, for sure, but so far quite worth it.
