I really enjoyed and loved the premise of the book, as well as the multiple timelines and multiple POVs. I found the focus on food in the book to be particularly moving, especially with the historical context and focus on foods origins in relation to cultures. The book ends with all of the loose strings tied up and all of the questions the book brought up answered. The use of foreshadowing was a little excessive, only because it made the reveals/twists in the book predictable. 
The reason I did not give this five stars is the same as many of the critiques I have seen -- the author tries to go to wide with the story and cover as much as she can as opposed to deep diving into the central story. 
Overall, an interesting read that I enjoyed, and I look forward to seeing the authors progression and refinement as a writer in the future.
