The Glass Ocean

                     Beatriz Williams, Lauren Willig, Karen White
                                     (Historical Fiction)

2 time periods,  3 women.
Sarah , in 2013, is researching her family history for a new novel she is trying to write.  Her great-great-grandfather was a steward on the Lusitania.  She finds a connection with a family named Langford and travels to England to meet John Langford , whose great-great-grandfather was also on the Lusitania.  They start digging in the family archives and discover some hidden family secrets.

In 1915, we meet Tess and Caroline, who are both on board the Lusitania.  Caroline is a first-class passenger who is questioning her marriage  and Tess is second-class passenger who is a thief trying to steal something from Caroline. 

There is intrigue, espionage, and romance in this novel.   However,  I find it difficult to classify it as a true historical fiction.  For me,  I need more historical facts than the time and place in which a novel takes place.  Also,   I do not enjoy romantic love stories, which this book had too much of. 
But still an enjoyable read.
