Elizabeth Peters - The Ape Who Guards The Balance (1998)

This is book 10 in the Amelia Peabody series. The Emersons are initially in 1907 England where Amelia is fighting the suffragette battle for equality and almost getting kidnapped in the process. Naturally her husband whisks them all off to Egypt, a location he considers much safer for his family - he's obviously learned nothing from the 9 preceding books.

Ramses is arrogant and annoying. Nefret continues to flirt with all and sundry. David is a doormat - sad, considering how stubborn and strong he began as. The trio find a papyrus and try to hide it from their parents, even though it puts all of them in danger. They insist they're adults, and being in their early 20s they are, but they continue to act like immature and foolish teenagers. By the end of the book they're doing better at being less secretive with each other, but not enough to keep themselves out of danger.

I was so happy to have Sethos back, but then Peters rudely took him away again in the first few chapters. I think that it soured the book for me. This is honestly a good book, a really fun book in the series but... I just really like Sethos, it's my romantic flaw.
