The Book of Lights

Not a book that you want to rush through, I found. My first thought was that The Book of Lights is markedly different from My Name is Asher Lev, yet some of the same themes dominate the book. What does it mean to be a Jew? What are one's responsibilities to one's family? Should one go through the motions or should one find one's passion? How can a person be both faithful to his family's traditions and faithful to making his way in the world? Important questions, all.
