Rashi is among the greatest of Jewish sages and is without doubt the greatest of the commentators on the Bible and Talmud. His daughters are among the very few medieval Jewish women whose names are recorded and known to this day, Joheved, Miriam and Rachel many traditional stories are told about them and it is partly these stories combined with her formidable knowledge that Maggie Anton has used to create a vivid and very readable set of novels. The first of the Trilogy begins in dramatic fashion in 1091 in Rashi's household the focus of the whole Trilogy is on the daughters relationships to each other and the father and mother, but mostly on the desire to engage with MItzvot (commandments or good deeds) and with Torah and Talmud study. In course of reading these novels you learn a lot about Rashi and economics and political life of eleven century France, but don't let that put you off the trilogy in general and book one Joheved in particular are enjoyable reads. Should you wish to follow up on what you have learnt then information on where to go is provided at the end of the book.
I would recommend this book with the one word of warning that if you are extremely religiously conservative you may find some of the sex sense too strong (albeit that they all take place within the context of marriage). Unless this applies too you then I am sure you will enjoy this book and even if you know something about Rashi and the Tosafot then you will still learn something from reading this book and have fun at the same time.
