A good read about a fascinating period in history and an entertainingly twisted royal family. However, as is sometimes the case in these dual narrator books, I found one of the two sisters (elder Berenice) much more interesting than the youthful Arsinoe. I wouldn't have cut Arsinoe out of the book entirely but I didn't think she was a strong enough character to be a co-protagonist and I wished I had more time with Berenice, who was a great character. A book solely from her vantage point, or maybe her and her mother, would have been awesome. 
 Still worth reading even if the majority of the Arsinoe chapters are pretty blah because the Berenice chapters are so good. Holleman also writes well stylistically.
