I've loved all the books I've read by Rhys Bowen and The Tuscan Child is no exception. It begins in Tuscany during WWII in December 1944 and takes the reader to an English manor house in 1973 and then back to Tuscany in the same period while interspersing with the struggles a downed WWII British Air Force pilot has in the Italian hills, trying to avoid the retreating German army. Some of it is a bit reminiscent of the Captain Corelli's Mandolin storyline. The only disappointment I had was that Rhys Bowen didn't include the delicious Italian recipes talked about and prepared in the novel.
Be warned though, you may want to book a flight to Tuscany after reading The Tuscan Child.
