I've been a serious home cook since I was a child [early 1970s] and these are the cook books that go the distance.

Book series that I enjoy reading at least annually.

I'm always a little sad at the end of a good book. A good series of books is much better!

The first series of books I ever got invested in was the original Nancy Drew series. The most agonizing series I've followed was the Earth's Children Series by Jean Auel. Twelve long years between books four and five. The most fun I've had with a book series was watching my pre-teen morph into a teen with the Harry Potter series, and yes, she attended a few of the "midnight release parties" at the book store.
