I have seriously mixed feelings about this book. While I appreciate books that highlight the women behind history's most important men (I adored The Paris Wife), I found this one a little difficult to stomach. 
 I don't know that much about Einstein as a person (as opposed to a scientist), but some of the words Benedict puts in his mouth seemed like a little much. It's entirely possible (and likely) that Maric fell into her husband's large shadow when they were married and after they had children, but some of the purely evil acts he commits against her in the book took the fictionalization of this couple's story a little too far, in my opinion. 
 I can understand that Benedict is taking creative license here, but I really didn't enjoy reading about the hateful man Einstein was by the end of her story.
