I'm listening to
Lionheart by Sharon K. Penman. Classified as historical fiction. It's about Richard the Lionheart. It's the first of two books Penman has written about Richard, the second being
A King's Ransom - which covers his return from the Crusades and his captivity.
I'm a huge fan of Penman's having read everything she's written. The above two books are the only ones she written that are available in an audio version.

I wish her Welsh Trilogy was also available but alas, no joy there.
Highly recommend!
