Well, that was a rather elegant solution to end the series on. I'm quite pleased with it. 
 Compared to the other books in the series, I found this one a bit uneventful. Which is why I'm only giving it 4 stars. The first half of the book passed slowly. It felt like a whole lot of blathering; excessive narration about nothing of interest or importance. It might have been this way for the other books and I was just better at skimming back then. Once I started skipping the boring bits, I enjoyed the book more. If you're really into long paragraphs detailing a character's clothing, than you'll probably not have the same issues that I had. 
 That said, I'm just now realizing that I can't remember anything that happened in the first half of the book. I think that's an indicator as to how slow the story was. It might have been better if the story had started at the halfway point. Once the characters were in Egypt, things were a lot more interesting and I'd have liked to have seen more from that location. 
 Avoiding spoilers here... Something terrible happens near the end of the book and it left me in tears. I can't remember the last time a book made me cry that hard. Because of it, I surged to the end--half in a rage that the author might end the series in such an unhappy way. 
 I want to add that I really enjoyed the sections from Biffy's point of view. I think those are largely what got my through the book. I wouldn't say they were more exciting, but perhaps it was the budding love that made them so enjoyable. 
 Before I end this review, I want to give a nod to the last couple pages. I just really enjoyed the way the author wrapped things up. The shift into changing times felt natural, and it allowed me to see the characters living out their days happily. But I also appreciated the nod to Alexia's daughter taking up the parasol and getting her own book series when she's older. Somehow it felt like a wink to the reader. I can't wait to read about Prudence, or whatever name she prefers to go by.

 Alexia falls just about the middle for me. She's not exactly useful in a fight, but she's not afraid to throw herself in the mix anyway. I gotta respect that. She makes due.
