Falling in love with a younger man while you are still married and then having a younger woman come along wasn't the best thing to happen to Mrs. Theresa Marshall.

A CERTAIN AGE began with an excerpt from a murder trial then moved to alternating chapters and told of the life of high society and how they adapted social protocol to whatever they wanted.

We follow Mrs. Marshall, Mr. Marshall, Captain Rofrano, and Miss Fortescue in the scandalous antics they were all involved in. Decisions had to be made and?? Sophie Fortescue had the most difficult decision, even though her father was the one that would be making the decision about who she was to marry.

Ms. Williams again perfectly portrays the time period and how women in wealthy families really didn't have a choice about choosing their spouse. After the marriage proposal was made, an investigation into the Fortescue family adds another layer to the book. The Fortescues are not who they say they are, and a house that Mr. Rofrano grew up in was part of their secret.

Once the secret was revealed and Sophie Fortescue was more outspoken, the book heated up with an ending that was oh so good with an unexpected twist.

I enjoyed the characters, but Mrs. Marshall and Mr. Fortescue were my least favorites. Mr. Fortescue was too controlling, and Mrs. Marshall was too sneaky for me.

A CERTAIN AGE was beautifully written as all of Ms. Williams’ books even though it took me a while to get connected, but it was still enjoyable.

The book's cover is stunning, and the book is patterned after an opera titled Der Rosenkavalie.

ENJOY if you read A CERTAIN AGE. 4/5

I liked this authors first book and liked this one as well. I did find it a little confusing going back and forth between time periods although they were short spans. The story is told through different characters each chapter. there are surprising twists by the end . You do get a fair amount of historical information about the time period, and the twists and turns are excellent.
