This is the seventh book in the Amelia Peabody series.
The Emersons are back in Egypt, having left Ramses and their adopted daughter Nefret at home in England. Unfortunately, even though they told no-one of their find, someone knows about the lost living Meroitic civilisation they discovered on their last excavation and they're determined to get the precise location. But, a mysterious stranger is equally determined to protect Peabody, although not so Emerson, who is abducted and later found with amnesia. This leads the group to Amarna, where Emerson thinks he's on the dig in 1884, before he ever met Peabody.
I didn't like the killing of the dog. It had been tortured and was terrified - they didn't need to beat it to death.
Other than that, the book was good, but not my favourite. I found Emerson to be much worse to Peabody than he was in the first book, he was very rough and often cruel. I kept hoping Amelia would give up on him and run off to someone nicer - I'm really not sure that Emerson is worth all the love and loyalty Amelia gives him when he does remember who she is. It was fun to have Sethos back. He's such an interesting character. I hope he has a larger role as himself in a later book - no, I don't believe the ending at all.
