The Light Over London by Julia Kelly

Cara is working for an antique dealer and learning a lot about how to identify them.  When she finds an old diary, he lets her take it home to read.  He doesn't plan on selling it so he gives her permission to return it to the family if she can locate them.

Gallery Books sent me a copy of this book to read for review (thank you).  It has been published so you can get a copy now.

She's reading about a woman during WW II and she thinks she might learn more about her grandmother this way.  Grandma doesn't want to talk about those days.

Louise's diary shows how she was all swept up by Paul in a young romance.  She even marries him when he comes home on leave.  Then she hears of his death and wonders why no one told her, she was his wife.  She finds out he was already married.  She goes to visit his first wife and finds she's not the only one fooled.  He's married others. 

Then Cara looks through other papers she found of Grandmother's and finds her secret...

Times of war heighten emotions.  You never know how long you will live, so you take your joy where you can find it.  Paul was a bigamist and that's not common but other consequences were.

This is a good historical read.  Louise and Paul would never had made it in marriage.  He wanted her home, having babies.  She wanted to work.  They fought about it before he left.  Now she's free to live her life as she chooses.  So was Cara's Grandmother.
