Probably less than 3 stars but idk. I liked the ending but the story basically had no depth up to that point. The characters were really flat and nothing happened. I hate when the book summary gives information for things that don't happen until literally the last 25% of the book; it just feels like a spoiler at that point. I feel like there was so much potential missed here. I love time travel and historical stuff mixed in but there was nothing to write home about.
