Paper Widow (Unabridged‪)‬

When a pampered socialite in post-Civil War Boston seeks adventure and romance, she finds peril, heartache, and tragedy along with it.  

Answering an ad in The Matrimonial News, she secretly marries by proxy but is widowed before she gets to meet her husband. The fact that she's naive and unskilled in the ways of love when she finally encounters the man of her dreams only adds to her situation.
