Hello fellow bakers

I have a quick question for you all.
At times I see the cake bible being referenced as a great go to book. So my question is who is the author of the cake bible ? I have come across 2 books named that but do not know which is the better book to purchase. I any of you can let me know that would be wonderful, I would love to have more great books for reference.

Thank you everyone,

Rose Levy Berenbaum
