If you like thrillers, Deborah Baker’s “tale of exile and extremism” is a true story with a new twist at every turn of the page. If you haven’t read a good biography lately, then too here’s your opportunity. And this is just for starters, since The Convert is ample nutrition for our minds, morals and politics. There are two main characters in Baker’s book. One of them is Margaret Marcus, daughter of a non-practising Jewish family from New York.
