It's not a fantastic book, but I enjoyed it a bit. It follows much of the life of John Saturnall from being cast out of his village with his mother for witchcraft to rising to Master Cook of a noble household. All set to the backdrop of the English Civil War between Charles I and Parliament. The plot and characterization are often simplistic and the author never really follows through on some ideas.
On the other hand I thought Norfolk was quite restrained with certain aspects of the story such as the political background. The Civil War, religious fanaticism, even the romance are more sub-plots that have an impact on the main character's life. The major focus is on the character being a cook. Here the author is restrained as well so the reader doesn't get overwhelmed with recipes and the like so you don't need to be a food aficionado to enjoy it.
To take inspiration from the title, the best way to read this book is to sit back and enjoy the feast.
