Jeffrey Marshall is a retired journalist and the author of three books, including Little Miss Sure Shot, a historical novel about Annie Oakley. He has been published widely in newspapers and magazines, including The New York Times and New Jersey Monthly, and was at various times a reporter, editor, feature writer, columnist and book reviewer.
During his career, Marshall was involved with every medium in journalism except television - newspapers, magazines, radio, newsletters and journals. He was a winner or co-winner of numerous editorial awards for magazine writing and design. He wrote a book about community reinvestment in the banking industry and published a volume of collected poems, River Ice, in 2009. He lives in Scottsdale, AZ, with his wife, Judy, and two dogs, Maggie and Blaze.

Suzy Perry, a lovely, accomplished older woman, has married into a new family in Westchester County, NY, after being widowed not long before in Atlanta. Her new husband, Dean Perry, is besotted with her, but his son, Alex, and daughter-in-law Lisa are troubled by how little they know about her. Who is she? 
Little by little, clues and tidbits of information persuade Alex that he needs to know more. As the questions pile up, Alex, a journalist, elects to hire a private detective to probe Suzy's past, without informing his father. Over time, it becomes clear that Suzy changed her name when she moved to Atlanta - and that she had been married for many years to a car dealer in Missouri who died suddenly shortly before she left.
Is all this innocent, or something more sinister? Once circumstantial, the evidence becomes more concrete - and then Suzy is on the run.

My thoughts 
Black Widow: highly venomous American spider which has a black body with red markings.
2nd meaning:woman who kills her husband or lover, especially one who kills multiple husbands or lovers.
Do we really knew the people in our lives as well as we think we do, after reading this I would say not so much, and after reading this I'm going to be a lot more safer when letting new people in , because after reading this I can definitely say this Don't ever let Suzy (or what ever her new name is ) into  your live because you might be welcoming a surprise that you wasn't looking for , in fact run the other way because she's like a praying mantis who killed their mate after getting what she wants all the time thinking she's the one that's been wronged and she's the innocent party. I do have to say that it was the cover that got me to pick up the book and this is the first time I've ever read a thriller where the main character is a black widow , in fact I don't think I've ever read one that has that in it,which made this so different from other thrillers I've read, and it was so easy to get lost into the story . I especially felt sorry for her new husband because he was a lovesick fool .With that said I want to thank Netgalley for letting me read and review it exchange for my honest opinion.
