Introductory books about Judaism

Hi,

I’m from Australia. My mother is Jewish, but I was not raised Jewish (no Bar Mitzvah). Her father, who migrated from Poland in the 1930s, died before I was born, and his wife (my Grandmother) was not very religious, so the tradition kind of faded. I have some extended family here who are still practising Jews, but I don’t know them very well. I feel an affinity with Jewish culture, but I am somewhat ignorant about the religion itself.

I would like to learn more about Judaism and relevant history etc. What is a good book to start with?

Many thanks.
